It was an extraspecial weekend for Anna Paquin and her family since it was her first time celebrating Mother's Day! They got a head start on the fun on Saturday, when they met up with friends for a party at a Malibu park. Anna and her husband, Stephen Moyer, took turns holding onto their boy and girl twins, whose names have not been revealed, and mingling with guests. The babies were born in September and since then have joined their parents for shopping trips and strolls along Venice Beach, though their sweet faces have been kept mostly under wraps. It hasn't been all about parenthood for Anna and Stephen, though, since they've also been working on the sixth season of True Blood. The series doesn't return until June 16, but you can check out pictures from True Blood season six now to gear up for the next installment!
