Charlie Sheen as his wife discovers she's pregnant with twin boys

Hollywood star Charlie Sheen is set to become a father again two times over after finding out his new wife is expecting twin boys.

Real estate agent Brooke Mueller, 31, is three months pregnant with twins, the Two And Half Men star confirmed.

Sheen told America's OK! magazine: '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.'

The babies will be Brooke's first time as a mother, but will be the fourth and fifth children for Charlie.

In a statement in August when the couple first announced her pregnancy, the Two And A Half Men actor said: 'Brooke and I are thrilled.

'She's the best stepmom Sam, Lola and Cassandra could ever hope for. Seeing her love and affection with those three, I know she'll be an amazing mom. Unless I bat 100 per cent, perhaps a boy awaits us.'

Sheen has two daughters Lola, four; and Sam, two; with ex-wife Denise Richards and a 23-year-old daughter Cassandra from a previous relationship with Paula Profit.

The pregnancy news was expected by friends after the couple started talking about having a family immediately after their nuptials.

Mueller said: 'Could you imagine if I really had triplets?. He'd be like, 'Whoa.'

The couple married on May 30th in front of 60 friends and family, including the actor's father Martin Sheen and mother Janet, Grey's Anatomy star Eric Dane and his actress wife Rebecca Gayheart (who introduced the bride and groom).

Sheen has two failed marriages behind him, to model Donna Peele in the 1990s and a bitter split from second wife Richards after four years of marriage in 2006.

Charlie Sheen custody battle turns ugly as he taunts mother-in-law over cancer treatment

Hollywood actor Charlie Sheen's custody battle took an ugly twist when he taunted his former mother-in-law over her cancer treatment, it has been alleged.

The former Young Guns heartthrob has been battling his ex-wife, actress Denise Richards, for visiting rights to their two daughters.

But with their divorce settlement becoming increasingly acrimonious, he was said to have launched an astonishing attack on her sick mother Joni, who is undergoing treatment for breast cancer.

Sheen allegedly told Miss Richards in an e-mail: "You are a pig. A sad, jobless pig who is sad and talentless and, um, oh yeah, sad and jobless and evil and a bad mom, so go f*** yourself, sad, jobless pig."

In another he wrote: "Go cry to your bald mom, you f***ing loser."

The name-calling incident mirrors the ugly split between fellow actors Alec Baldwin and Kim Basinger.

Baldwin, 49, was banned from seeing their 11-year-old daughter Ireland after calling her a 'rude, thoughtless little pig' for refusing to take his phone calls.

Sheen, 42, and Miss Richards, 36, met on the set of the 2001 film Good Advice but ended their four-year marriage in November last year.

Since then they have clashed over custody arrangements for their daughters Samantha, three, and Lola, two.

Miss Richards has previously accused her ex-husband of looking up child porn on the Internet while caring for the girls and of not being capable of looking after them.

She added when they returned from weekends with their father they were 'sad and upset.'

Sheen accused Miss Richards of driving a wedge in his relationship with their children.

She has already won the right to choose two nannies to accompany the children to his home and has applied for a court order to limit their visits to days rather than overnight stays.

The pair have also clashed over the children's medical needs with Sheen refusing to let them have commonplace jabs.

Their ongoing battle caused Samantha's doctor Jeannette Levenstein to resign, saying: "because of differing philosophies I cannot continue to treat her."

Sheen, who followed in his actor father Martin's footsteps, rebelled in his youth.

As one of the Brat Pack during the 1980s, he had a playboy reputation and was exposed as a drug user and regular client of Hollywood madam Heidi Fliss.

Miss Richards has claimed he still has drug and gambling problems as well as still using prostitutes.

Sheen has denied the allegations.
