Anna Paquin is gearing up to welcome not one, but two babies this year, but that doesn't mean her schedule is slowing down too much.

The pregnant "True Blood" star and her HBO co-star and husband, Stephen Moyer, arrived at London's Heathrow Airport in London on July 19, with Paquin's growing baby bump on full display.

The pair announced in April that they were expanding their family, and it was later revealed that twins are on the way for the couple, who married in 2010.

The couple's co-star, Sam Trammell, knows a thing or two about twins, considering he and his girlfriend Missy Yager welcomed twin boys in August 2011.

"It's so interesting that 'True Blood' has become, like, the 'twins' show," Trammell told Us Weekly in June, adding that he's excited for Paquin and Moyer.
