Jack Black Married: Actor Gives Post-Marriage Sex Advice To Angelina Jolie And Brad Pitt

It may have only been a week since Angelina Jolie and Brad Pitt announced their engagement, but pals of the famous pair are already speaking out about the long-awaited nuptials.

During a recent interview on "Entertainment Tonight" to promote his new film, "Bernie," actor Jack Black shared some post-marriage sex advice for the couple, who he has known for several years.

"I think the sex actually improves once you've sealed the deal," said Black. "It gets better. Maybe not for everyone, but for me, once we sealed the deal and we shut off all the exit holes and said, 'No, this is it. We're in it for life,' then we really let loose." Black has been married to Tanya Haden since 2006.

Despite the fact that Jolie and Pitt have traveled all over the world together, Black suggested that the couple go to Big Sur, Calif. for their honeymoon. "Leave the eight kids with the nannies just for a couple days," he quipped.
