Tommy Lee announced his engagement to his long-time girlfriend, Sofia Toufa, on Monday via Twitter. According to reports, this will be the 51-year-old Motley Crue drummer’s fourth wedding.

"There comes a time in a man's life when you just know your partner is for LIFE!! Say hello to my fiance and soon to be wife, SOFI," Lee tweeted, referring to Toufa's stage name.

Toufa also shared the news on Twitter, writing: "I'm something that rhymes with Beyonce!"

Lee and Toufa have been in a relationship since 2010. Lee had told People at the time: "I was born in Athens, but I've never really dated a Greek girl ...She could be the one."

Lee was previously married to model Elaine Starchuk, actress Heather Locklear, and "Baywatch" star Pamela Anderson. He has two sons with Anderson, 17-year-old Brandon and 16-year-old Dylan. The on-again, off-again relationship between Lee and Anderson, following their 1998 divorce, ended in 2008.

Lee was also reportedly engaged to Prince's ex-wife, Mayte Garcia, but the couple did not get married.

In 2007, Toufa worked as a backup singer in “Rock Star Supernova,” a reality television-formed supergroup band formed by Lee and Gilby Clarke among others.

Lee and other members of Motley Crue recently announced that they were planning to part ways after playing together for 33 years. But, before officially calling it quits, the band will head out on a farewell tour, with Alice Cooper opening for the band.
