Red Carpet Confidential: Selena Gomez Sparkles At UNICEF Ball While Justin Bieber Dines Out

Selena Gomez shows off an impressively fit back in a slinky Dolce & Gabbana gown during the UNICEF Snowflake Ball held Tuesday at Cipriani 42^nd Street in NYC.

Joined by a lookalike female cousin — and not on-again, off-again beau Justin Bieber — she fetches $40,000 for her auction items, netting the charity funds to accomplish their mission of saving and improving the lives of children worldwide.

Two backstage concert experiences are “sold,” with the bidders selected slated to attend her Acoustic Concert Benefiting the U.S. Fund for UNICEF and go backstage to meet her. Plus, they will get a dozen VIP tickets and backstage passes to her NYC concert in January. Fun times!

The 20-year-old beauty mixes and mingles with Katy Perry, new mom (again!) Uma Thurman, Kelly Ripa and hubby Mark Consuelos, Matt Lauer, Allison Williams, Tea Leoni, Selita Ebanks, Barbara Bush and Jenna Bush Hager, and Real Housewives of New Jersey‘s Caroline Manzo.

Kelly is on a mission to get Katy’s autograph for daughter Lola, 11.

“That’s so tacky, right?” she says. “But I think I have to.”

Matt can’t wait to see the performance by Tony Bennett, but also getting face time with Selena.

“I grew up in a house where Tony was on the record player all the time. I like him as a person; I love him as a performer.”

Of seeing Selena tonight, he says, “I’m looking forward to it. I think that’s a classic case of generations coming together.”

Meanwhile, Justin is across town treating his entourage to a low-key Italian dinner at Asellina, where he texts and takes phone calls at his table. He noshes on ravioli, truffle fries, margarita pizza, calamari, and requests vanilla gelato with his pie for dessert.

Not only does Justin stay away from alcohol (he’s only 18!), but he also picks up the tab and leaves a tip that makes the server “very happy,” an eyewitness tells me.  

Later in the evening, the couple reconnects at Marble Lane, Hollywoodlife.com reports.

Tonight and tomorrow Justin is in town to perform at Madison Square Garden. Will Selena be in the audience?
