You don't get to be one of the biggest pop stars on the planet without keeping tabs on what other artists are up to - so perhaps that's why we caught Britney Spears showing up to the Staples Center for Alicia Keys' big concert!

Brit did her best to keep a low profile as the security guards waved her through the back entrance and then out again after the show wrapped up. In fact, if she hadn't been riding in her big, white Escalade, we probably wouldn't have recognized her at all!

Still, we're sure Britney had a great time - after all, Alicia puts on one heck of a show! Wouldn't it be great if they got together to work on some music?

Kate Hudson graces the cover of People Magazine's 19th annual "100 Most Beautiful" issue - it's her fourth time on the list.

Also in this collection of pretty people, which seems to exist to remind us regular people just how regular we are: Halle Berry, Patrick Dempsey, Salma Hayek, Jessica Simpson, and Alicia Keys.

So, the scoop on their cover girl Kate? ... She says she may consider breast implants after she's finished having kids. She says, of her son Ryder's long hair: "Why is it so weird? My son likes his hair. He likes his hair long because it's like his father's." And last but not least, she's quit smoking.

The mag's "Hall of Fame" - those who've grabbed spots on the list numerous times - includes: Nicole Kidman (9 times), Angelina Jolie (6 times), Brad Pitt (8 times), Matthew McConaughey (5 times), Halley Berry (12 times), and George Clooney (8 times).

They's also got "The New Classics" list aimed at making people old before their time! Miley Cyrus tops the list, of course; Ashton Kutcher, Kate Beckinsale, Christina Applegate, and Sarah Silverman are also part of that group.

And the "Heating Up" list names Rumer Willis as "The It Girl."

Also in the "100" are: Carrie Underwood, Jennifer Lopez, Mary J. Blige, Norah Jones, and Josh Groban -as well as TV stars Tina Fey (30 Rock), Vanessa Williams (Ugly Betty), Mariska Hargitay (Law & Order: SVU) and Marcia Cross (Desperate Housewives). The entire cast of Gossip Girl is featured as well as the ladies of MTV's The Hills, Lauren Conrad, Audrina Patridge, Whitney Port and Heidi Montag.

Although completely friendly to our French photogs, Alicia kept her mouth shut in preparation for last night's concert at Le Zenith!

Did any of our readers catch the show? If so, how was it?

Before the actual Grammys on Sunday - when Amy Winehouse took home an incredible five awards, all deserved! - Clive Davis had a little pre-Grammy bash, sponsored by Intrigue Spirits, at the Beverly Hilton Hotel on Saturday.

Only a couple people showed up, though - ya know, like Lindsay Lohan...

Someone named Fergie?

Who looked the best?

Looks like everyone's got J-Lo on the brain these days - yesterday, a bunch of photographers (only one of whom was ours!) accidentally mistook Alicia Keys for the impregnated ingenue as she left the gym! Fortunately, Alicia was able to take the mistaken identity in stride like a true professional - although after Tommy Lee and Kid Rock's best efforts to disrupt her VMA performance, we can't say we were too surprised by her composure!
