True Blood star Anna Paquin welcomed twins Charlie and Poppy with husband and co-star Stephen Moyer, last September and she showed off her post-baby at the season six premiere in Los Angeles this week. Walking the “blood red” carpet in a form-fitting David Koma LBD, we had to ask what her secret was for snapping back into her svelte shape. The trick? Stroller duty! ”I have always been pretty active, but pushing a double jogging stroller is not specifically easy,”  Paquin told InStyle.com. “It’s a good workout. I’m not kidding, push that stroller!” On it! Don’t miss Paquin return as Sookie Stackhouse when True Blood premieres June 16 at 9 p.m. on HBO.

True Blood’s two hottest vampires amped up the sex appeal last night, and for a good cause! Real-life married couple Anna Paquin and Stephen Moyer attended Tom Ford’s cocktail party at his Beverly Hills boutique, held to benefit Project Angel Food. The organization delivers meals created by professional chefs to homebound people suffering from serious illnesses like HIV/AIDS. The couple, who just welcomed twins in September, will return to HBO this summer for the sixth season of the salacious, New Orleans-based vampire show.

Where will we find Sookie when the lusty vampire series returns on June 26th? “She’s told both the boys in her life to basically go away and never come back, as one does when one finds one’s been lied to,” Paquin teased. Click through to see Nicole Richie, Taylor Lautner, Sienna Miller and more stars at last night’s hottest parties!
