Katherine Heigl won't address rumors that her days on Grey's Anatomy are done, but she does admit that family is her top priority now.

"I took those 3 months off and I realized how very, very important my family is to me and I want to be more available to them," the 31-year-old star told People Thursday at the ongoing ShoWest convention in Las Vegas, where she was on hand to accept an award for Female Star of the Year.

Heigl took a break from the hit ABC series after she and husband Josh Kelley adopted their daughter, Naleigh, in September.

"I think I'm just gonna try and keep it a little more mellow," she said of her future plans, "and be a little bit more of a mom, since that's a big part of my life now."

Heigl suffered a wardrobe malfunction during her acceptance speech when one of the straps on her red dress broke and nearly exposed her breast. Thankfully, the night's emcee, Billy Bush, quickly came to the rescue by holding the strap in place while she completed her speech.

"Oh my," Bush later posted on his Twitter page. "Hosting showest awards in LV. Heigl comes up to get award, dress strap breaks...I hold her top on while she accepts!"
