Pregnant in heels!

Mila Kunis walked the red carpet with co-star Channing Tatum to promote their upcoming film Jupiter Ascending at CinemaCon last night in Las Vegas, and the actress attempted to disguise her growing baby bump in a loose navy dress. The cat's out of the bag, girl, so you should just rock it!

The brunette beauty and fiancé Ashton Kutcher are expecting their first child, and according to reports, the couple want to tie the knot before their little bundle arrives!

"They are planning to get married in L.A. in April. They just want it to be made legal so they are happy with a registry office," a source told The Sun.

"Mila, especially, wants it to be very low-key, with just their family there and a BBQ in their garden afterwards. She doesn't want to do anything showy or over-the-top," the source added.

She's got a lot to smile about these days!
