It wasn’t all work and no play for the celebs who made the trek to San Diego’s 40th Annual Comic-Con. After they were done promoting their various projects during the day, they spent their nights partying like rock stars – or more accurately, vampires.
All Comic-Con long, celebs had plenty of reasons to celebrate. Thursday night saw MySpace and IGN.com’s bash for the upcoming horror film Jennifer’s Body at the Manchester Grand Hyatt’s Kin Lounge. The film’s star Megan Fox and screenwriter Diablo Cody took in cocktails in a poolside cabana (as did New Moon stars Ashley Greene and Kellan Lutz) while listening to a solo acoustic set from Panic! at the Disco’s Brendon Urie.
The hottest ticket on Friday night was the mammoth Wrath of Con party at the Hard Rock Hotel’s Woodstock Terrace, thrown by film site IESB.net. Surprise guest Daughtry performed live – even singing through a megaphone – and dedicated his set to his wife. A fight even broke out – but it was all part of the festivities: Heroes star Masi Oka and Star Trek’s John Cho took in a full-scale TNA wrestling match at the center of the party.
Finally, the stars spent Saturday night at Entertainment Weekly and SyFy’s soiree atop the Hotel Solmar. Wardrobe-coordinated couple Jennifer Love Hewitt and Jamie Kennedy were curled up in a private cabana, while Hayden Panettiere perched poolside in a plunging purple dress with new gal pal and Heroes costar Madeline Zima.
And there was plenty of vamping going on when True Blood actors Sam Trammel, Rutina Wesley and Alexander Skarsgard encountered Ian Sommerhalder and his castmates from the upcoming vampire drama The Vampire Diaries.
When celebs like Kristen Bell wanted to relax during daylight hours, they hit the Wired Café at the Omni Hotel, where they grabbed lunch, cocktails and various goodies, including Batman emblazoned Haviana sandals. Anna Paquin showed up with boyfriend and True Blood costar Stephen Moyer (who joked that in L.A. they never leave the house), where Lutz continued to dodge prying fan eyes, hiding under a wig while hanging out with New Moon’s Noot Seear.
