Katherine Heigl makes her baby bump debut and talks pregnancy cravings

Katherine Heigl debuted her newest accessory on Wednesday night (Aug. 10) as she stepped out in Los Angeles: her blossoming baby bump. The 37-year-old actress, who is expecting a boy with husband Josh Kelley, looked gorgeous cradling her latest curve in a figure-flattering white dress at the 2016 Television Critics Association Summer Tour Party.

Katherine is clearly enjoying her first pregnancy. She opened up about her maternity experience so far as she took part in a panel session to promote her upcoming CBS drama Doubt at the TCA event.

"I feel great!" said the star. "I am very, very grateful, actually, because you never know. I've had a really easy – knock on wood – pregnancy so far. Just tired and hungry."

There's one food Katherine is craving above all others – "Donuts! On sets they always have craft service and have three boxes of donuts every day. I just try to take a bite or two… or six," she admitted, adding: "The sugar thing has been really bad – and I'm not generally a sugar person. On occasion I'll have dessert, but every day – I mean, if you put a cinnamon roll in front of me, I get ugly!"

Katherine and her husband Josh are set to welcome their son in January. The couple are already parents to two daughters, Naleigh, seven, and Adalaide, four, whom they adopted in 2009 and 2012 respectively.

No one is more relived to be expecting a baby boy than musician Josh. "He's just surrounded by women," Katherine said. "It's me, the two girls, my niece Madison loves with us in Utah and she's a 14-year-old girl, and then my mum.

"The poor guy, he's literally surrounded. I think he's just really excited. His brother had a baby last February, a little boy, and they're already talking about their golf foursome!"
