Radar Online reported on Jan. 15 that Heather Locklear and her off-and-on fiancé, Chris Heisser, called it quits after a "never-ending" fight while the actress was on a break from rehab over the holidays. "They started fighting on Christmas Eve and Chris took off. They continued fighting until after Christmas. Then Chris moved out of her house before the New Year," said a source. According to the insider, the duo fought over "the same issues" they've always had: "She doesn't trust Chris at all and if she's not with him she thinks he's with other women. If she's alone, she assumes the worst and then starts drinking. They fight over text and phone calls until he comes back and it usually escalates." According to the webloid, the "Melrose Place" star believes her problems are in the past now that Chris is no longer in the picture: "She's been in and out of rehab and nothing has changed, so she decided to change what she thinks the source of the issue is — Chris!" said the Radar insider. "That's why she hasn't returned to rehab. She's rationalized that she doesn't think she needs treatment now that he's out of her life." People magazine later reported that, according to a friend of Heather's, the actress is now "doing outpatient rehab at home" and "has broken up with Chris." Said the People source, "By her making this move, it gives her a great reset button on what is most important and that is her sobriety." The insider adds that Chris has not helped Heather "sustain her goals of sobriety." Said the pal, "She set goals of sobriety two years ago and those were not working with him in the picture."

Brie Larson and Phantom Planet frontman Alex Greenwald have parted ways after an engagement of almost three years, multiple media outlets reported on Jan. 11. "They have taken a step back from their engagement for the time being but they remain close," a source told People magazine.

Arie and Lauren are currently expecting their first child, a baby girl.

Richard Madden and Ellie Bamber have called it quits after 18 months together, The Sun reported on Jan. 12. "They're both absolutely gutted but it was a decision made for the best. They were arguing almost daily towards the end and, despite considering couples' therapy, it became evident there were far too many issues that could not be fixed," said a source. "Richard is the toast of Hollywood at the moment and understandably wants to let his hair down. … Ellie is a bit quieter and wants to focus purely on her work," continued the insider. "It felt like their day-to-day lives were increasingly becoming worlds apart."

In a statement sent to People magazine on Jan. 10, a Paris-based publicist for Grace Kelly's granddaughter, Charlotte Casiraghi, and her fiancé, Dimitri Rassam, denied early January reports that the couple called it quits. "Mademoiselle Charlotte Casiraghi and Monsieur Dimitri Rassam harassed by the scandal press, formally deny all unfounded rumors of their separation which are being circulated," read the statement. "The explanation of this cynical and false information is simple: to portray conflict where there is not and never was, with the goal of monetizing it, because the announcement of a separation always motivates good sales. Given the harmful nature of this rumor for themselves, their children and loved ones, they have agreed to ask their lawyer to initiate all legal proceedings, where possible before criminal courts." The duo welcomed a baby boy, Balthazar, in October.

Irish actor Allen Leech and actress Jessica Blair Herman, who starred on "The People v. O.J.

The bride and groom recruited former "Glee" co-stars Darren Criss and Lea Michele to perform at the ceremony after the string quartet that had been hired for the event bailed at the last minute because of the uncharacteristic downpour that rocked Southern California in early January, leading to unsafe driving conditions.

"Chilling Adventures of Sabrina" co-stars Ross Lynch and Jaz Sinclair are fueling persistent rumors that they're more than friendly co-workers.

(Courtney, by the way, reportedly romanced Ross from 2015 to 2017.) Asked about the speculation that they're involved, Ross told "Entertainment Tonight," "Jaz is like, my closest friend right now" — but didn't deny a romance. Both have been posting sweet sentiments about their close relationship on their social media channels since late 2018. For example, Jaz celebrated Ross's birthday by sharing a slideshow of photos of them spending time together away from the set of their hit Netflix series: "Happy Birthday to my favorite.

When one of Rob's Twitter followers suggested he was only hanging out with Alexis to get back at Chyna, he responded, "Me and Alexis known each other for 5 years so stop with that. … Damn i was just trying to eat some good food."

"Everyday with you is filled with joy and laughter. (even when we get heated every night over who has to get out of bed to turn off the hall light). 8 years! In a little over a month it'll be 8 years together. Those being packed full of ups and downs. (90% ups) I'll always be thankful that you walked into my 24 hour resturant when I first moved to LA. I was a waiter aspiring to be an actor. You were an assistant aspiring to be a writer. Now look at us! Living the dream together. Finding the strength in our unity with the loss of [our dog] Orion. To finding out on my birthday in the dirty parking lot behind the resturant I worked at (at that time) that I lost my first big job / cut to you holding me later that night whipping away my tears and telling me it was only the beginning. You've never faltered in being a supportive, loving, stubborn, sensitive rock in my life. Here's to another 100 years of traveling the world, stealing your socks and loving our babies, whether their dog babies or actual babies. I'll love you forever. Happy anniversary, my darling."

After the late-night host commented on their obvious chemistry and asked if she set boundaries with her castmate, the actress replied, "I did. We had just come back from a hot yoga class and went to his apartment and we ordered pizza, and it's kind of like, 'Oh, hot yoga, pizza. What's happening?' It was right before we shot the movie … just getting to know each other. … And I felt something. So I looked at him, and I was like, 'Noah, it's not gonna happen between us.' … I felt that for the show to do well, we had to be best-friend professionals. And so I was like, 'It's just not gonna happen,' and he was like, 'Yeah, it's not gonna happen.' And I was like, 'Great!' So we kind of did what we did in 'To All the Boys,' the movie. We kind of made a contract and set boundaries. I'm so happy that we did that because the movie turned out great, and now we're doing a sequel. So I have to work with him again. So imagine!" She then admitted that they "still have the spark." We wonder how Lana's boyfriend, "Pirates of the Caribbean: Dead Men Tell No Tales" actor Anthony De La Torre, feels about that!

(Lindsay said her former great love didn't cheat on her.)

I didn't take it super-serious because he lived in Nashville [and I live in Los Angeles]. Then I was like, 'Oh man, I really like this guy.' … When I realized this, I was like, 'I'm supposed to be getting a [second] kidney transplant in nine days and I'm on dialysis. What do I do?' So I texted him being like, 'You need to come out to L.A. by the end of the week or this is never gonna happen.' And he was like, 'What's going on?' [I said], 'I'm going to be out of commission. Come next Tuesday. It's totally fine. I'll be fine.' And I didn't tell him anything. … Then the next day, he texted me, 'See you on Saturday,' and I was like, 'Oh, that's so romantic.' He's like, 'I'm presenting at this award show,' and I was like, oh, he totally, like, called whoever his people are and was like, 'Get me to L.A. by the end of the week,' just for me.
