Charlie Sheen's pregnant wife has been hospitalised with premature contractions.

Brooke Mueller — who is due to give birth to twin boys in April — was rushed to a Los Angeles hospital for treatment but is expected to be released soon.

Charlie's publicist Stan Rosenfield said: "Brooke is at a hospital, where she was admitted with premature contractions — which is not all that uncommon for someone at this stage of pregnancy, especially with twins.

"She's fine and is expected to be discharged from the hospital soon."

Sheen — who already has daughters Sam (four) and Lola (three) with ex-wife Denise Richards and 24-year-old daughter Cassandra from another marriage — and Brooke got married last May and announced they were expecting twins in October.

The 'Two and a Half Men' actor said: "I'm truly blessed. I'm already the proud father of three beautiful daughters, and I'm delighted that they'll now have two little brothers. Life doesn't get any better than this!"
