Guitarist Rob Patterson popped the question over the weekend

Carmen Electra may be giving matrimony another whirl.

The "Meet the Spartans" actress is reportedly engaged to boyfriend Rob Patterson, according to a People source.

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

Patterson, 37, is the former touring guitarist for KoRn. He reportedly proposed over the weekend in Las Vegas to celebrate her 36th birthday on April 20. They've been seeing each other for less than a year.

Electra has been married twice before: to NBA star Dennis Rodman and former Jane's Addiction and Red Hot Chili Peppers guitarist Dave Navarro.

Her latest credits include "Scary Movie 4," "Date Movie" and "Meet the Spartans."
