Expecting twin boys in April, Brooke Mueller Sheen is starting to pop! Paparazzi snapped a side view of her growing belly as she went grocery shopping Wednesday afternoon in Beverly Glen, Calif. Dad is actor Charlie Sheen.

When the couple’s sons arrive this spring, they will join sisters Cassandra Jade, 23, with Charlie’s ex-girlfriend Paula Profitt, as well as Sam, 4 ½, and Lola Rose, 3, with ex-wife Denise Richards. The couple announced the pregnancy in August.
