Ali Larter pregnant with second child

Actress Ali Larter and her husband Hayes Macarthur are set to become parents for a second time.

The former "Heroes" star revealed the news during an appearance on America's The Tonight Show Starring Jimmy Fallon, Friday noting that the last time she visited his programme in 2010, she was pregnant with her first child, son Teddy, reports contactmusic.com

Larter said: "That (interview) went so well, so you know what that means..." and stood up to reveal her growing baby bump."

She also added that it hasn't been easy trying to hide her pregnancy, especially since she has been working on a new action TV series, "Legends".

"I've been trying to hide it (the bump) as much as I can. And you know, when you're in the public eye, it's really scary in the beginning," she said.

"I was still shooting my spy drama, Legends, where I have to be a covert spy - and a spy in my real life too. So I'm wearing blazers and push up bras and everything you can do to distract as the bump is growing," she added.

Larter and her writer-actor husband walked down the aisle in 2009.
