Katy Perry was seen leaving Claridges in London today. The singer did some shopping and spent a little time with fans, too.

Chace Crawford was spotted on the set of 'Gossip Girl' in NYC this afternoon. They shoot a lot of the show's scenes outside, don't they?

And last, but certainly not least...Keanu Reeves! We don't see him too often - and that's just the way he likes it. Here he is hanging out on a loading dock in NYC yesterday afternoon.

I can't IMAGINE trying to date as a celebrity. Especially when you get as much attention as Jennifer Aniston. But what is she supposed to do: stay inside her house? 'The Switch' star was spotted out with another guy last night, but she's been linked to him before: Chris Gartin, according to E! News.

Jen and Chris enjoyed a three-hour dinner at Madeo, where onlookers tell us they very much looked like a couple.

"They were on a date," says a fellow diner. "She was all cozied up to him and they were talking closely and laughing."

Our source says the two arrived at about 7:30 p.m. and sat at a table secluded from the main dining area. When they left around 10:30 p.m., our source says the two covered themselves with a sheet in their chauffeured car to avoid the snaps of the 15-plus paparazzi waiting outside.

Chris, if you recall, is the ex-husband of one of Jennifer's friends. Her friends' relatives complained to the press (in Australia, where they live) about the relationship.

Well, eventually I'm sure we'll know who Jennifer is dating (since she can't really keep it a secret if things get serious).

So sweet!

The entire Affleck clan tried to beat the heat yesterday with a day out in Pasadena at The Huntington Library, and of course, looked positively precious while doing so!

Brothers Casey and Ben were spotted playfully pushing each other around, and little Seraphina and Violet got to spend time with the grandparents!

We STILL can't get over how happy those two little girls always look! Jen's gotta be one of the best moms in Hollywood!

Hope you guys had fun!
