Talk about having no time to lose! Denise Richards is reportedly engaged to Richie Sambora even though the rocker is technically still married to his “Melrose Place” wife.

The Bon Jovi guitarist is said to have popped the question last month and the couple are planning to wed as soon as Richie’s divorce from Heather Locklear is finalized.

Richie is believed to have broken the news to his band members earlier this month.

A source told the National Enquirer, “He said, ‘I asked Denise to marry me and she said yes!’ He told everyone to get used to having Denise around.”

Meanwhile, Denise is said to be locked in a new custody battle with estranged husband Charlie Sheen - over their pet dog.

The former Bond girl - who has two children with Charlie - let the “Three And A Half Men” actor look after their dog Bettie for a period of time but now claims he is refusing to give her back.

The “Wild Things” actress is blaming Charlie’s new lover Brooke Mueller for conspiring to take the beloved dog from her.

A source said, “Denise thinks Brooke doesn’t want Charlie to hand the dog back and she is furious.”
