There's a fine line between interesting and TMI — and Sunrise Coigney, wife to Mark Ruffalo, may have crossed it. The 40-year-old mom of three (the couple are parents to son Keen and daughters Bella and Odette) spoke to Allure at the NYC premiere of her husband's new movie, Now You See Me, on May 21 about becoming a brunette and ended up (over)sharing Ruffalo's naughty response to the hair color change.

"I'm normally a blonde, but after 17 years, you have to shake it up a bit," the French-American actress told Allure. "I just felt like I was too blonde. I turned 40 and I thought, I need some changes."

Fortunately, the Kids Are All Right actor approved. "Mark has always been asking me to do it," she said. "He'd say, 'Just do it!' His initial reaction? 'Now the curtains match the carpet!'"

In an interview with Men's Journal, Ruffalo, 45, talked about how he met Coigney: literally on the street."[I] saw her and was like, I'm going to marry that girl," he said. "All I had was my decency, wit, and charm -- I didn't have anything. When I met her, she was like, 'You don't have a driver's license, you don't have a credit card. What is wrong with you, dude? I can't be with you!' I was living in a converted garage, and she was there for that, she was game. She believed in me. She was like, 'I know you're a really good actor,' and I was like, 'You haven't really seen me act yet.' And she was like, 'I just know it, I can tell.' "
