Sibling revelry: Now that Anna Paquin and Stephen Moyer are altar-bound, Anna’s older brother has given his blessing to his sister’s True Blood costar joining the family.
“I absolutely approve! Steve will be an amazing husband to Anna and a great brother-in-law,” Andrew Paquin told PEOPLE at Saturday’s Tribeca Film Festival premiere of his directorial debut movie, Open House, which also happens to star Anna Paquin and Stephen Moyer.
Assuming the role of the protective older brother, Andrew, 33, has no problem with the 40-year-old English actor marrying his 27-year-old sister. In fact, Andrew and Moyer have become close buddies themselves.
