Katherine Heigl stepped out in style at the premiere of her new drama, Unforgettable, and the actress and mother of three said she got a little fashion help from her adorable daughters.

"I had three dress options for tonight and I asked my 15-year-old niece, [who] lives with us, I asked her what she thought and she's like, 'The one with the cleavage,'" Heigl joked. "And my 8-year-old said, 'Can I see?' and I showed her and she goes, 'Well you can’t wear that! Your boobies are showing!'... So that dress was out."

The actress eventually opted for a white, curve-hugging, off-the-shoulder gown that looked absolutely stunning. She was joined by her husband, musician Josh Kelley, for the premiere, saying the premiere also served as a date night for the cute couple.

Heigl and her husband are the proud parents of three children -- daughters Naleigh, 8, and Adalaide, 4, and son Josh Jr., 3 months. According to the former Doubt star, she and her husband go out of their way to embarrass their little ones.

"We love to embarrass them," she marveled. "Josh has great, great embarrassing stories. He drives my niece to the bus stop every morning and he wears my pink robe and he gets out of the car waves her off on the bus [so] all of her classmates get to see him in his pink robe… It's great."

Heigl has been promoting her new film, Unforgettable, for weeks, and she says the most unforgettable thing about the process has been tackling the challenges of being a new mom while on a nation-wide press tour.

"Trying to pump or breastfeed between interviews [has] been really interesting," she said. "It’s a whole new world for me."

Heigl said that she even found herself having to pump in the bathroom while filming Jimmy Kimmel Live on Tuesday afternoon.

"It’s really awkward, honestly," she said. "[But what's] best for the baby is best for the mom!"
