Carmen Electra engaged

Carmen Electra is engaged to her boyfriend Rob Patterson, her rep has confirmed.

"He told friends three days ago that he got engaged," a source said. "The ring is a black diamond set in white diamonds."

The two -- who have been dating for less than a year -- became engaged in Vegas over the weekend while Carmen was celebrating her 36th birthday there.

This will be the third marriage for the actress-model, who was previously married to rocker Dave Navarro and, briefly, to NBA star Dennis Rodman.
