{babes} Flirts vs. tweets at Victoria's Secret party

Not even Victoria's Secret supermodels can distract Twitter founders Evan Williams and Biz Stone from their smartphones. The pair was seated at the Victoria's Secret runway-show after-party at Lavo on Wednesday next to a bevy of gorgeous angels, including Adriana Lima, Lais Ribeiro, Anja Rubik, Erin Heatherton and Flavia de Oliveira.

But a spy reports, "They were right next to the hottest models in the world, but they didn't pay them much attention. They were more interested in their phones, chatting to each other and meeting Facebook co-founder Eduardo Saverin. Biz left early, and Evan hung out, chatting to Adrian Grenier."

"Entourage" star Grenier also introduced himself to Karolina Kurkova, but a witness chuckled he "looked disappointed when she, in turn, introduced him to her husband."

While the supermodels shared a table, queen bee Alessandra Ambrosio insisted on her own booth and spent the night dancing and taking photos with guests.

Model-loving rival bands Kings of Leon and Maroon 5 ignored each other at the show. At the party, Maroon frontman Adam Levine cuddled up with his model girlfriend, Anne Vyalitsyna, while the Kings hung with beauties including Lily Aldridge, the fiancée of frontman Caleb Followill.

After watching Lily walk in the show (which CBS will air Nov. 30), Caleb joked to us, "I'm ready for a beer now. That got me a little hot under the collar." The two ended up at Avenue with "Transformers" star Rosie Huntington-Whiteley and her actor boyfriend, Jason Statham.

Also a hit with the girls were Gerard Butler and Akon, who was flirting with VS beauty Selita Ebanks. An onlooker said, "He was whispering in her ear."

Serena Williams turned up with a leg in a cast, following surgery on her foot. Spies said that she managed to dance but that when she left, she "struggled to get up the stairs, due to being on crutches."

Other partygoers included Katy Perry -- who replied with a huge smile and a wink when we asked her about her wedding to Russell Brand -- Paris Hilton, Vin Diesel, Adrien Brody and Maxwell.
