Ashton Kutcher and his pregnant fiance Mila Kunis jetted off to Iowa over the weekend to visit with his family, and X17 photographers snapped the duo at LAX on Sunday evening after their quick trip to his hometown.

Kunis made her first red carpet appearance since the pregnancy news broke at Cinemacon in Las Vegas, and though she hid her baby bump in a loose navy dress, it sounds like she's going to start showing any day now!

But don't expect her to get chatty about it! "She is so private she probably won't ever talk about it -- at least not publicly," a source tells E! News. "She and Ashton don't want to share this with the world. They've been like that for their entire relationship. Ashton knows what it's like having a very public relationship and doesn't want it again."
