Kenan Thompson

Perennial performer Justin Timberlake is returning to the Saturday Night Live stage this weekend to pull double-duty as a host and musical guest. According to these promos, he will also be in charge of makeup, sound, cameras, and pretty much the entire show. That is, as long as Kenan Thompson is by his side. At one point, Thompson steps away and the usually collected Timberlake gets flustered, inviting us to watch Friday Live Pie. Whatever it's called, I'll be tuning in to see JT host for his fifth time this weekend.

It's no secret that pop sensation Justin Bieber has screaming legions of fans all over the globe, but I didn't imagine Kenan Thompson to be one of them. Bieber is taking to the stage this weekend as both the musical guest and host of Saturday Night Live, and his promos with Thompson prove there really is no demographic limitation for Beliebers. When Bieber accidentally pushes a button, his face appears on all the screens in the studio, much to the embarrassment of Thompson — who may or may not have been stalking Bieber for three years.

James Franco stepped out yesterday to support his short documentary Saturday Night during the Tribeca Film Festival in NYC. The piece, which already won awards at the SXSW Festival, is a behind-the-scenes look at the week leading up to hosting SNL, and stars from the show like Kenan Thompson, Will Forte, and Jenny Slate were there to attend the premiere with James. After the red carpet, James headed inside for a screening and a Q&A session where he said the goal of his piece was to find out "what that mysterious comedy process was." James's directorial effort was one of two projects he had playing at Tribeca, as he also starred in a movie created by one of his NYU professors called William Vincent.

I've seen my share of awkward moments on The Martha Stewart Show — she's spun around a stripper pole, not so subtly insulted Rachael Ray, and threw down rhymes with Snoop Dogg about "green" brownies. Awkward moments and all, I can't ever turn away from Martha. Maybe it's because regardless of how weird it seems to everyone else, it never is to her.

She took it to an entirely different level on yesterday's show though. At a roundtable discussion with comedian Kenan Thompson, chef Marcus Samuelsson, and nutrition and weight management expert Dr. David Katz, Martha tells Kenan he should ask Dr. Katz a question because, "You're a little overweight." I cringed and looked away, finding myself in even more disbelief because it didn't even occur to her that she had done anything wrong. Oh, Martha.

The MTV VMAs was a party in itself, but when the show ended all the celebs spread out around town to keep the good times and red carpet highlights rolling. Lady GaGa was joined by Kristin Cavallari, Russell Brand, Jessica Alba, and Diddy for a bash at Avenue, while an Epic Records dinner at the Waverly Inn brought out Jennifer Lopez, Marc Anthony and Shakira. Pete Wentz hosted friends at his bar Angels & Kings, and InTouch's ICONS + IDOLS soiree gathered Kim Kardashian, Whitney Port, Gerard Butler and even Jon Gosselin. Jay-Z hit the official MTV post-awards celebration, as did Justin Timberlake and a tummy-baring Rihanna, before heading to 1Oak for an after-after party with Jessica Alba and Katy Perry.
