Mila Kunis made a quick stop at Ralph's in Studio City, CA, to stock up on groceries on Monday. She carried multiple bags out to her car and covered her growing baby bump in a casual outfit. Mila's been keeping quiet about her pregnancy since the exciting news was revealed last month, though she did make a recent red carpet appearance at CinemaCon. Her baby bump wasn't the only thing on display during the press event, since she also showed off her diamond engagement ring from Ashton Kutcher. She and Ashton are making headlines for their personal life as well as their professional lives; she's making a cameo with Ashton on Two and a Half Men, and the first clip of the real-life couple sharing the small screen was released this week.
