Charlie Sheen and Brooke Mueller-Sheen’s newborn son, Max, is still in the hospital after being diagnosed with a heart condition shortly after his birth, Entertainment Tonight sources have learned.

Charlie and Brooke, who wed in a ceremony in Los Angeles last May, revealed that they were expecting twins in October. Max and his twin brother Bob were born March 14.

Poor little guy :( Get better soon, Max……

UPDATE: A rep for The Sheens has confirmed that Baby Max is still in the hospital nearly three weeks after being born, but contrary to ET’s report, the infant is not being treated for a heart problem. He just needs to gain a little more weight before he can join the rest of his family at home, the publicist says.

“Charlie and Brooke’s infant son Max remains in the hospital, not because of a heart condition as reported, but because he has not gained the weight necessary to leave hospital,” Sheen’s publicist, Stan Rosenfield, says in a statement. “Max is expected to reach the weight requirement shortly and will join his brother at home.”
