Anna Paquin is one trendy mama-to-be.

The True Blood star, 30, showed off her chic maternity style -- and her growing belly! -- while walking her dog in Los Angeles Friday afternoon. Her bump looked bigger than ever under the fun, printed sundress she sported, which she accessorized with a dark blue cardigan, oversized sunglasses and black ankle booties.

Us Weekly first broke the news in June that Paquin is expecting twins with her husband and True Blood costar, Stephen Moyer.

The actor, who plays Bill Compton on the beloved HBO drama, opened up to Us later that month about his and Paquin's double baby joy. (Moyer, 42, is already a dad to a son, Billy, and a daughter, Lilac, from previous relationships.)

"I love my kids beyond anything," Moyer gushed. "They're the best things ever, and having two more is just going to be even more crazy [and] cool!"
