Life’s suddenly looking hunkydory for “Two and a Half Men” wildman CHARLIE SHEEN – thanks to daddy-o MARTIN SHEEN, whose peace-making ploy finally worked when he convinced his son’s new wife, BROOKE, to stop taking Charlie’s lead in despising ex-wife DENISE RICHARDS, hold out an olive branch – and get her twin boys BOB and MAX acquainted with half sisters SAM and LOLA.

Insiders say Martin’s warned Charlie he could seriously damage the emotional well-being of his kids – and that he’d better start loving them more than he hates Denise.

Mellowed by love for his twin boys, Charlie had actually told pals he wanted to make peace with Denise as his girls’ mother, but was worried Brooke might get jealous.

That’s when Grandpa Sheen stepped in. The wily master negotiator’s finally got everyone acting civilized, but longtime observers of the Sheen scene wonder how long the peace can hold.

Stay tuned.
