LAUREN Graham has been hiding a big secret on the Parenthood set!

The actress has revealed she’s dating her on-screen brother, Peter Krause, off-screen!

The 42-year-old opened up about her love life in the October issue of Redbook magazine — where she insisted the transition from costars to lovers was easy.

“One of the things that’s been so fun is that it’s so easy,” she said.

“It’s a lot, to work with somebody and spend time with them, too.”

Graham says she and Krause first met each other 15 years ago.

“I think we liked each other [but] he asked me over to his house to play a board game — and that’s exactly what we ended up doing,” she said. “So I was like, ‘This guy doesn’t like me. Who actually plays a board game?’… The timing wasn’t right.

“I don’t think either of us was ready.”

“Nobody knew about it for awhile, because we like to be at home, cooking and not going out,” Lauren added. “I’ve also been really protective of it, because it’s important that you can buy us as brother and sister on the show.”
