SHEEN begs DENISE on bended knee: Save my sons from Bimbo BROOKE!

Desperate to create a safe, loving family atmosphere for twin sons Bob and Max if crazed sniff ’n’ snort mommy BROOKE MUELLER fails rehab yet again, CHARLIE SHEEN’s brainstormed a secret WINNING strategy, and it’s a shocker: The Warlock’s actually proposed marriage to ex-wife and mom of his other two kids, stunner DENISE RICHARDS!'

“When Denise took Charlie’s twins into her home last December after troubled Brooke entered rehab once again, Charlie suddenly realized it was the very first time his sons had lived in a healthy environment – and the first time he’d been able to begin building a relationship with them,” said a source close to the star.

“And Denise loves those twin boys just like her two daughters by Charlie, Sam and Lola. When the boys were returned to Brooke, Denise told a pal, ‘I felt like my heart was being ripped apart.’ Not only is she totally loving to the boys, she’s helped Charlie to build a relationship with them. And she’s agreed that if they can talk a judge into giving her custody, she’ll happily care for the twins full time. Denise even agreed to Charlie’s request to adopt the boys, but legal experts advised there are too many complications to even consider it.”

Here’s the kicker: Even though Charlie’s turned on his fabled charm, the one scheme Denise says she will NOT entertain is his plan to remarry.

“That’s going too far…it’s never going to happen,” she confided to a close friend.

But Charlie, famed for his persistence, keeps showering Denise with gifts and loving attention.

Said the friend: “He’s simply refusing to give up on his idea of a happy remarriage that will reunite his children in a safe and happy home – and he’s telling Denise he won’t take ‘no’ for an answer!” Stay tuned.
