Zooey Deschanel, Victoria’s Secret Show in Celebrity Twitpics (Photos)

The Glee girls try “tebowing,” backstage with the Victoria’s Secret Angels, and more stars’ Twitter photos.

David Letterman turns the camera on Annie Leibovitz, the Glee girls do some “Tebowing,”  and Ashton Kutcher reunites with his That ‘70s Show boys. Plus, more of the stars’ Twitter photos from this week.

Alessandra Ambrosio

Brazilian beauty Alessandra Ambrosio may be a Victoria’s Secret Fashion Show veteran, but she’s still excited by the backstage buzz. With reporters, photographers, hair and makeup artists, and fellow models running amok, Ambrosio took a moment to offer her Twitter followers a glimpse of the chaos. She tweeted a photo of herself in a pink satin robe and wrote, “Getting ready for the @VictoriasSecret #vsfashionshow !! Its starting to get crazy backstage!!”

Doutzen Kroes

While her fellow Victoria’s Secret Angel was getting her hair primped and her face painted, Doutzen Kroes spent the minutes before Wednesday’s Victoria’s Secret Fashion Show hanging out with newfound fashion designer Kanye West. Kroes tweeted a photo of herself with the hip-hop star, writing excitedly, “With @kanye backstage! #VSFashionShow here we go!”

Dianna Agron

They may have avoided planking and they may have even resisted the forces of leisure diving, but the stars of Glee have apparently bought into the newest Internet phenomenon: "Tebowing." Dianna Agron and costar Jenna Ushkowitz struck the same kneeling, praying pose that the Denver Broncos’ Tim Tebow did last month after leading his team to a comeback victory over the Miami Dolphins. Agron tweeted a photo of her and Ushkowitz in the pose and asked her followers, “Do you Tebow? #tebowing”

Mario Lopez

If anyone could run the New York City Marathon with an injured friend—and stop to sign autographs, dance some salsa, and film an interview—it would be Mario Lopez. The Extra host still managed to finish the race in four hours and 20 minutes and proudly tweeted a photo of himself and his hard-earned gold medal at the end of the marathon. “I did it!” he tweeted.

Zooey Deschanel

Zooey Deschanel has apparently had a lot of girl time since her split from Death Cab for Cutie frontman Ben Gibbard. The New Girl star was bonding with some similarly coiffed ladies on her new Fox sitcom. Deschanel tweeted a photo via Whosay from the set and exclaimed, “Look at all the brunettes with bangs on the set of #newgirl! Cc: @msjunedianne @hannahsimone and Lizzy Caplan”

Mariah Carey

After Mariah Carey and husband Nick Cannon became the happy parents of twins Moroccan and Monroe in April, Carey embarked on a mission to regain her formerly fit figure. So far, she’s succeeded, losing 30 pounds and gaining a new gig as Jenny Craig’s celebrity spokesperson. Carey posted a picture via Twitter of her new slimmed-down body. She also included a link to a USA Today article in which talks “about weight loss and her hope to inspire others,” the tweet read.

Felicity Huffman

Felicity Huffman got philosophical on set with Desperate Housewives costars Eva Longoria and Marcia Cross on Monday. She tweeted a photo of herself and her fellow Housewives and wrote, “Me,@reallymarcia,@EvaLongoria on set: my question to come: it’s a good one!” The question Huffman asked all her Twitter followers was: “Looking at your life, from the outside, what advice would you give yourself? Marcia, Eva and I gave an answer, what’s yours?”

Ashton Kutcher

Ashton Kutcher is a man of many faces, as this six-part photo that the Two and a Half Men star tweeted in L.A. earlier this week demonstrates. Kutcher, who has since quit Twitter in the wake of a Joe Paterno faux pas, struck goofy poses with his former That ‘70s Show costars Wilmer Valderrama and Daniel Masterson. Of the reunion, Kutcher tweeted simply, “Boys.”

Joy Behar

Despite her daughter’s divorce troubles, Kris Jenner didn’t let the drama dissuade her from being the proper former mother of the bride. The Kardashian momager performed the simple courtesy of returning Joy Behar’s wedding gift during her guest spot on Behar’s HLN show. The host tweeted a photo via Whosay of the two laughing about the unopened blender and Behar joked, “Dear future guests: if you’re wondering, I still need a toaster oven.”

Emily VanCamp

Emily VanCamp is the star of ABC’s hit fall drama Revenge, which takes place in the Hamptons. But the actress was on the sandy beaches of the show’s North Carolina set when she tweeted a photo of herself and a costar. “On set with one of my faves @Gabriel_Mann! Nolan Ross and Emily Thorne up to no good as always :)” she tweeted. Her emoticon was probably the only smiley face in sight once the cameras started rolling on the murder mystery series.

Emmy Rossum

The star of Showtime’s Shameless, Emily Rossum got caught in the rain while filming the series’ upcoming second season in Chicago. Unfazed by the weather, she tweeted a photo of herself near the “L” train line and said, “In front of the el in the rain in Chicago #shameless”

David Letterman

Photographer Annie Leibovitz usually stays behind the camera. But during her appearance on The Late Show With David Letterman this week, she found herself in front of the lens as Letterman tried his hand at photography. “I hate this!” she protested as Letterman snapped away. The photos from the impromptu shoot left much to be desired and proved Letterman shouldn’t quit his day/night job anytime soon. The Late Show tweeted the photo and called it “Portrait of Annie Leibovitz by David Letterman.”
