Benjamin Millepied & Natalie Portman

Natalie Portman and her choreographer husband are dancing their way through her second pregnancy after taking up tap lessons.

Benjamin Millepied has revealed he and his wife are learning all about tap dancing after finding themselves with a little spare time after moving to Los Angeles from his native France this past summer.

"We recently started taking tap dancing classes," he tells Access Hollywood Live. "She has an advantage; she has more experience than me but I'm catching up... I'll get there."

Millepied and Portman met on the set of Black Swan in 2009 and the actress gave birth to their first child, son Aleph, in June, 2011. The couple wed in August, 2012.

News of their second child leaked out after the actress showed off a baby bump on the red carpet at the Venice Film Festival in Italy in September.

"I thought I was gonna be able to hide it a little longer and then we got there and I was like, 'It's not hide-able any more... The stomach wants to be out...'," she recently said. "And now it's out in the world."

And she also insisted she's not as far along as some people seem to think she is: "I'm a small person in general so you show a lot faster and a lot more when you're small," the 35-year-old star said.

"Everyone thinks I'm about to pop and about to give birth at any minute, but I have months to go."

The family is back in Los Angeles, where Millepied is working with the L.A. Dance Project, which he founded in 2011.
