The same day she announced her engagement, Carmen Electra flashed her new ring from fiancé, guitarist Rob Patterson, at Thursday's Dos Equis party in Austin, Texas.

The ring features a 1.5 to 2 carat black diamond solitaire with a platinum band inset with white diamonds, estimated to cost about $100,000.

Her rep confirmed to Usmagazine.com Thursday that the two — who have been dating less than a year — were getting hitched.

Electra, 36, talked to Us about their relationship in March, after she joined him in Europe where he was working.

"We're good," she said. "[We wandered around] just by ourselves, so it was kind of fun to get lost and just be together. Very romantic."

This will be Electra's third trip down the aisle. The actress wed rocker Dave Navarro in 2003; the two called it quits in 2006.

She and NBA star Dennis Rodman eloped to Las Vegas in 1998. Their marriage was later annulled.
