The biggest stars on the small screen are in New York City to give TV execs a taste of what they’ll be watching this fall. Last night, InStyle and Untitled Entertainment teamed up to host a cocktail party for some of television’s most familiar faces and their biggest fans. “I came here straight from Cannes,” said Vanessa Hudgens, who mingled with Californication‘s Carla Gugino, Top Chef‘s Padma Lakshmi and the stars of The Vampire Diaries. While Hudgens is focused on her movie career, she isn’t ruling out a return to TV. “I’ve been on an adventurous kick, so I’d love to guest star on Man vs. Wild or Survivorman,” said the High School Musical alum. “I think it would be so much fun!” Click through the gallery to see all the stars who joined in the celebration at our annual Upfronts bash.
