The expectant couple were snapped Sunday returning to LAX, just one day after the twosome landed in Iowa for a quick visit with Ashton's family.
Mila, 30, tried to conceal her tiny baby bump under lots of layers—including two scarfs, a baggy shirt and an oversized blazer. The pregnant Jupiter Ascending star also appeared to be recycling Saturday's travel look, right down to the aviator sunglasses, loose, ankle-length blue jeans and Timberland boots.
Mila's fiancé, on the other hand, switched his travel ensemble up only slightly. When landing in Iowa Saturday and then back in L.A. Sunday, the 36-year-old Two and a Half Men had on a multicolored cap, leather jacket, black, textured pants and black sneakers. He appeared, however, to have switched shirts during his quick trip to his home state.
And while we'd all love to hear about the Saturday festivities at casa de Kutcher, it doesn't seem very likely. The famously private couple has yet to comment publicly on their exciting baby news, and as a source tells E! News, Mila "is so private she probably won't ever talk about it—at least not publicly."
"She and Ashton don't want to share this with the world. They've been like that for their entire relationship," adds the source. "Ashton knows what it's like having a very public relationship and doesn't want it again."
