Who knew they were gal-pals?

January Jones and Eva Mendes met up for a low-key dinner date at Mercato di Vetro in West Hollywood on Thursday night, but they opted to leave the restaurant separately to avoid causing a paparazzi frenzy.

The “We Own the Night" star has just retuned from a trip to Paris, where she was caught canoodling with new beau Ryan Gosling -- who's currently hard at work on The Gangster Squad -- in between shooting her upcoming flick, Holly Motor.

In other news, the Mad Men star was recently named one of the 25 Least Influential People of 2011. Ouch.

Now that he's officially single again, Ashton Kutcher has plunged himself into work on Two and a Half Men.

The New Year's Eve actor must have a lot more free time now that he doesn't have a wife to come home to, but he doesn't seem too anxious to dive into the dating world just yet.

While back home in Iowa for Thanksgiving, throngs of girls reportedly threw themselves at the former That 70's Show star while he was bar-hopping, but he was all about keeping to himself.

Meanwhile soon-to-be-ex-wife Demi is also busying herself with work post split, and she was even spotted enjoying a dinner date last Saturday with her LA florist, Eric Buterbaugh -- the two are reportedly "just friends."

But where's Avril Lavigne's beau Brody Jenner? Nowhere in sight.

The "Complicated" singer reunited with ex-hubby Deryck Whibley for dinner at Madeo in Hollywood.

In recent weeks, we haven't seen Avril and Brody hanging out as much, and now with this late-night reunion, we have to wonder if they're still going strong. Plus, a few weeks back, the singer and her surfer dude were involved in a bloody brawl at the Roosevelt Hotel. Too much drama, perhaps.

Although Lavigne and Whibley are divorced, they sure look cute together!

After being married just over a year, Russell Brand and Katy Perry are already facing those pesky divorce rumors, but the sexy British star appeared on The Ellen DeGeneres Show this week to finally set the record straight!

Brand jokingly tells Ellen on the alleged split:

"What? She should’ve of told me. Yeah, there are always rumors aren’t there. In the end you have to just not engage with Internet technology, which is difficult because a lot of the nude women websites I quite enjoy. But they’ve had to go. I’ve treated the whole Internet now like it’s a wicked little liar. Yeah. I am really happily married."

The Arthur star adds:

"I heard that rumor because you know if your job is to be on Telly and show off somebody will go there’s a rumor. Like someone that works with you. It’s called publicity or PR. There is a rumor. What is it? You’ve split up. Oh, no. Am I enjoying? Yes. Where am I now? You’re here. Good, good. Well, Just keep me informed. Being famous is like a little bit of you is taken away and goes off and lives on it’s own and does what it wants. I wish it would do more interesting things…."

Perry also denied reports of a breakup, Tweeting Wednesday night: "First I'm pregnant & then I'm divorced. What am I All My Children?!"

So now that those nasty divorce rumors have been cleared up, will the couple be starting a family in the New Year?

"I would like one. I love those little babies in the beginning. They’re so lovely in that bit. Me and Katy are godparents to two twin boys ... They are just a year old. At first they were boring. They were just essentially little fluid factories. Generating fluids. No regard for what I was wearing."
