Mila Kunis has been tight-lipped about her pregnancy but the 30-year-old can't hide her baby bump forever, right? Ever since news broke that Kunis and her fiancé Ashton Kutcher were expecting their first child, all eyes have been glued on the actress' belly.

Usually when Kunis is spotted out and about in Loa Angeles, her growing tummy is hidden under a baggy shirt but recently the "Ted" actress (and her bump) was photographed leaving an L.A. grocery store.  

Kunis was casually dressed in a long black maxi skirt, a loose-fitting white shirt, a denim jacket and a scarf. As she carried groceries to her car, paparazzi were able to catch the first signs of a baby bump. Check out the photos here and here.

Kunis and Kutcher, who are super-private, have yet to confirm their engagement or baby news and they most likely won't, a source told E! News. It's no secret that the couple prefers for their relationship to stay out of the headlines.

"I've learned that there are a lot of things in your life that really benefit from being private," Kutcher previously told Elle magazine. "And I am going to do everything in my power to have this relationship [with Mila] be private."

The actor was referring to his very-public marriage - and then divorce - to actress Demi Moore. Even though the two may never publicly acknowledge Kunis' pregnancy, a source close to the actress told OK! magazine back in January that the couple had been trying to get pregnant and are very happy about the baby.

"Mila and Ashton have been trying for a baby for months," the source said. "She's gained 10 pounds and is taking pregnancy vitamins. The buzz is that she is looking like she could be carrying a baby. Lately, you can't wipe the grin off Ashton's face! The atmosphere around them is just electric."
