For the third time since Friday, Britney left the house to attend a dance class yesterday. Yay! Hope for those still waiting for the big Britney come back! The Millenium Dance studio has been Brit's second home for the past few days, and even though it's been a while since she showcased her moves anywhere other than a nightclub, she's probably still got it. She was also seen entering the studio clutching a Kabbalah book. Hey, church one day, Kabbalah the next. Whatever works! Now, if only she could work on getting a stylist...I kid, I kid, baby steps.

NYC Meatpacking District's Pastis held court for Cameron Diaz and friends for lunch yesterday afternoon. (Perhaps, in rumor-y dreams, she was gabbing about her recent friend time with JT.) The actress' upcoming projects seem to be entirely limited to the Shrek Empire, so I assume she's got some time for leisurely lunches and paycheck spending at upscale boutiques. Rough life. Also, I'm not sure, but I think celebrity Manhattan is some sort of bizarro world -- where is everyone? Is that a bike on the ground next to her? Though I'm no NYer, I did live there for a few years and sometimes it confuses.

Matt Damon is busy shooting The Bourne Ultimatum in NY and our own PRSugar was lucky enough to see him in action on the set, fake blood and all. It's not easy to have the courage to ask a celebrity for a picture. To hear what happened when she finally got up her nerve (and to see a couple more pics, including Joan Allen on the set) just click here.

Christina looked mighty cozy in her giant pink scarf, sweats and golashes while heading to the airport after her long week in NY. While in the city, she celebrated, performed and partied her heart out, so we can't blame her for looking like she wants a nap. From there she's headed up to Canada for a few shows, and then it's back to the states. Hopefully she'll get a little shut-eye between now and then!

This season of Idol may not have picked up much steam yet (seriously, is one crying girl really the season's highlight so far?), but that could change with tonight's guest -- Gwen Stefani. Last month we heard that glam Gwen was going to perform, but it turns out that the contestants will actually all be singing songs that have inspired Gwen throughout the years. Considering this is a woman who has garnered inspiration from both Madonna and The Sound of Music, the song choice could be all over the map. We're just hoping that little cutie Kingston is in the audience!

Hey, it's Jessica Alba on the set of her upcoming psychological thriller, The Eye! How exciting! You can just feel the jubilance oozing out of Jess! Oooor, not. In fact, it's been some time since we've seen smiley happy Alba. Well, she hasn't been on a red carpet that we've seen in months (since October? Could that be right?), so maybe it's some sort of celebrity withdrawal. At least Fantastic Four comes out in a few months, that should give her the glam fix she needs.

Lohan may have spent a cozy (celebrity gossip rag code word alert!) evening with James Blunt last week, but this weekend she was back to her old tricks -- picking up the broken pieces of Stavros Niarchos. Yes, once again Linds was next in line for The Stav after he and Paris broke up. Judging from this latest bout of friendcest (or, as the case may be frenemycest) you'd think there were only like three young, single, hot men in LA. Though, maybe Stavros' parents will appreciate this new fling better than the last one? As if it will last that long.
