Tommy Lee is engaged to former Vine star Brittany Furlan

Tommy Lee has put a ring on it!

The Mötley Crüe rocker, 55, is engaged to former Vine star Brittany Furlan, 31. Furlan took to social media on Valentine's Day to show off her stunning bling, an enormous, heart-shaped center stone encircled by even more diamonds.

"Best day of my life!!!! I can’t wait to get to spend forever with my best friend," she wrote of the happy news, adding that her diamond engagement ring "certainly beats chocolates!"

Lee shared a beachside selfie with "his baby" Furlan last month while the pair vacationed in Cabo San Lucas, Mexico.

The couple has been linked since last June, yet Furlan played coy at the time when asked about her romance with Lee.

"He's a great dude," she told Entertainment Tonight.

The engagement marks the first for Furlan and the fourth for Lee. The drummer was previously married to model Elaine Bergen from 1984-1985; actress Heather Locklear from 1986-1993; and actress Pamela Anderson from 1995-1998.

He shares two sons, Brandon, 21, and Dylan, 20, with Anderson.
