They don't call him McSteamy for nothing!

On Saturday night Eric Dane and wife Rebecca Gayheart dined at Hakkasan in Beverly Hills with some friends, and the Grey's Anatomy hottie happily posed for photos with a few young and giggly female fans.

Maybe Rebecca is just used to this by now, because she didn't look that jealous! Though we're sure she'd draw the line at actually taking the picture for the girls though...

Lady Gaga hosted and performed on Saturday Night Live over the weekend, and though we saw her in a pair of absolutely crazy outfits earlier in the week at rehearsals, she kept it pretty conservative with a sparkly black number. Well, conservative for her -- we can still see her underwear!

Gaga performed her new single "Do What U Want" with R. Kelly and she also sang "Gypsy," but it was her skits with the rest of the cast that were her best work.

Gaga dressed way down to play an Apple store employee in the "Waking Up With Kimye" bit, and which featured Nasim Pedrad as Kim Kardashian and Jay Pharoah as Kanye West. Gaga poked fun at herself, at one point saying, "Honestly, I don't care about fashion. I think people who try too hard with their outfits are maybe hiding something. Like come on, dress like a person." Ha! Check out her videos below:

Anne Hathaway turned 31 last week, but she's still celebrating her birthday!

The Oscar-winning actress and hubby Adam Shulman met with her Dark Knight Rises director Christopher Nolan at Mr Chow in Beverly Hills on Saturday night, and they were also joined by fellow Dark Knight star Michael Caine and Sidney Poitier. Talk about a mature dinner group!

We know there's a baby bump in there somewhere, but Gwen Stefani kept it pretty well hidden when X17 photographers snapped her at Kingston's soccer game on Saturday!

Hubby Gavin Rossdale wasn't at the game, as he was in Boca Raton, Florida for the 2013 Chris Evert Pro-Celebrity Tennis Classic. On Sunday the singer tweeted, "flying back home. the best journey ever. thx @ChrissieEvert x congratulations on your charity we're all happy to be there for you."

And speaking of sports, it looks like they have a little Beckham on their hands:

Rather than stopping by a brothel or causing a ruckus in a hotel room, Justin Bieber was on his best behavior in Los Angeles last night.

The Biebs dined at Izaka-ya and left the restaurant just after dark, but the night before it sounds like he had quite the rager! The singer threw a party at his Calabasas pad on Friday, and the cops came out to the home three times after neighbors complained about the noise, according to TMZ.

Bieber was reportedly hanging with rapper Snoop Lion and about 100 other guests, and the website also reports that one neighbor filed a police report against the Biebs for disturbing the peace.

Kourtney Kardashian took son Mason and daughter Penelope to the Aquarium of the Pacific in Long Beach on Saturday, and it looks like everyone had a blast! And not only that, but in between juggling her two young kids and trying to keep it low key in the crowd, Kourt was able to Instagram a pretty pic of some jellyfish.

But where was baby daddy Scott Disick? The other day he was tweeting about cars and plugging a lingerie line (and this was NOT something from the Kardashians collection), and as far as we know he wasn't hosting any ragers in Vegas over the weekend. What gives?

A spirited Brandi Glanville needs help to her car after celebrating her 41st birthday at Flamingo in Beverly Hills.

When asked what she consumed for her birthday dinner, Glanville's friends respond for her, "Krupa on risotto" and "two glasses of wine." Glanville has no comment when asked about Joanna Krupa wearing a "Team Rimes" t-shirt.

But who was picking out clothes for who?

Ashlee Simpson and boyfriend Evan Ross went shopping in West Hollywood on Friday, and the duo kept it monochromatic in black and grey threads.

The couple have been keeping it low key since their first appearance together in July -- in fact, we hadn't seem them together in so long we were beginning to wonder if they had split! But just the other night they attended the BandFuse: Rock Legends video game launch at the House of Blues, looking very lovey dovey.
