The 42-year-old star is expecting a child with wife Brooke Mueller.

Sheen has three daughters - 25-year-old Cassandra Jade Estevez, whose mother is Sheen's former girlfriend Paula Profit, and two girls with ex-wife Denise Richards.

Sheen and Ms Richards are still embroiled in a bitter custody battle over three-year-old Sam and two-year-old Lola.

Sheen - who has starred in films such as Platoon and Wall Street, and appears in US sit-com Two And A Half Men - and Ms Mueller, a property investor, tied the knot in late May.
