Charlie Sheen has slashed his support payments to his ex-wives Brooke Mueller and Denise Richards in half. The 'Two And A Half Men' star - who has daughters Sam, 12, and Lola, 11, with Denise, seven-year-old twins Bob and Max with Brooke and also Cassandra, 31, with his ex-partner Paula Profit - is having "financial trouble" and has cut the huge sum of money he was parting with each month for the upkeep of his kids, according to TMZ. The 50-year-old star has come to an agreement to pay 'around $25,000 a month' to the actresses, who were said to be receiving $55,000 each up until now. Furthermore, the report suggests that Brooke - who split from the star after three years of marriage in 2011 - and Denise, who he wed in 2002 and divorced in 2006, wanted to avoid a hearing in court because it could have led to payments being reduced to as little as $10,000 per month each. Meanwhile, Charlie said recently he regrets not being "more involved" in his children's lives. He said: "I regret not using a condom one or two times when this whole thing happened. I regret ruining 'Two and a Half Men'. I regret not being more involved in my children's lives growing up ... But, we can only move forward from today, and they wouldn't call it the past if it wasn't." And the actor - who revealed in November that he was diagnosed with HIV four years ago - says telling the world about his diagnosis was "like being released from prison". He said: "It was like being released from prison ... and we unearthed the stepping stones to a rubicon of change."
