Mischa Barton strolled down Robertson Blvd. yesterday with UK radio personality Fearne Cotton, shooting an interview for Cotton's upcoming celeb interview program to air on ITV2 in England.

So we've never heard of Ms. Cotton and while she's got quite a cute face, we can't see anything of the rest of her body under that frumpy frock. Meanwhile, Mischa seems to continue to lose weight and was looking quite hot -- and literally hot! -- velvet shorts in August??!!

Hopefully to record a new song with Lady Gaga! Fingers crossed.

Our girl Brit returned to the recording studio again, most likely to work on some Glee-related tracks, but we're still hoping the Circus singer will release new music before summer's end.

Meanwhile, the blonde bombshell has been looking SO sexy lately! A tank top and short shorts that show off her terrific tan? Add on a warm smile and you've got a perfect ten!

Aww, who knew Lil Wayne loved Lindsay Lohan?

The rapper - currently serving a year in prison on weapons charges - has a website created by his friends entitled Weezy Thanx You, which publishes letters Wayne writes in prison.

Guess who got a shout out in today's entry? LiLo!

Wayne wrote: "Hey Lindsey, glad it’s over doll. I should have written her huh?"

Okay, apparently he spelled her name with an "e" instead of an "a," but still! It's the thought that counts.

Singer slash songwriter John Mayer has always been somewhat of an athlete!

The "Gravity" singer hung out with his personal fitness trainer in Studio City this afternoon and part of their workout included a friendly game of basketball! That Mayer. Such a playa!

And good to know Jen Aniston's ex is still exercising nonstop - check out those guns!

Hollywood celebs always have the cutest kids! And this weekend moms Victoria Beckham, Ashlee Simpson, Reese Witherspoon and Kourtney Kardashian all brought them out for the world to see...

Question is, who's the cutest! I mean I heart Deacon's facial expression, but Bronx is absolutely adorbs!

Infamous ladies' man David Spade has done it again -- the miniature comedian stepped out for lunch with a gorgeous girl who would never give him the time of day if he weren't, well, rich and funny.

Of course, "rich and funny" tops just about every woman's list of most attractive qualities, so if he has two of the top categories does it really matter if she can never wear heels?

Nickelodeon star Victoria Justice was bright-eyed and smiling after a plane ride home from New York where she co-hosted Macy's End of Summer Blowout in New York's Herald Square.

The busy Victorious star may not be as well known as her iCarly counter-part, but with adorable looks and a bubbly personality, we think she may give the Disney pop tarts a run for their money!

The hot and heavy Twilight stars have leased a romantic pad in Bel Air together and we couldn't be more envious!

Rob Pattinson and Kristen Stewart's new lakeside house is 28,000+ square feet and includes one large main house (with 4 bedrooms and 4 baths) as well as a recently remodeled two story guest house (which has an additional master bedroom and bath), not to mention a private parking area...

Talk about a secluded hideaway! And how much does it cost a month? According to the property's official website, $22,500/month. Damn! Not that they can't afford it.





And equally - if not more - impressive: Scarlett Johansson and Ryan Reynolds' new home together!

The happy newlyweds recently purchased The Wong House (roughly 2,835 square feet) in the hills of Los Feliz for an estimated $2,900,000. Uh-huh, that's right. Did you expect a luxury condo?

ScarJo and Ryan's dream house includes an oversized swimming pool with views from downtown LA all the way to the ocean. There's also a giant master bedroom (with built-in mini garden) and two children's bedrooms that were converted to a library and office. There's also a guest bedroom and three full baths.

Jealous?
