Tommy Lee Kissing Hot, Much Younger Mystery Girl

Tommy Lee's post-Mötley Crüe years look a lot like he's still on the road picking up hot chicks ... like the super young brunette who was all over him after a dinner date.

The 54-year-old extremely blessed drummer had a smokin' pair of long legs and burgundy lips Wednesday night in Calabasas -- and they belong to a 30-year-old ex-Vine star Brittany Furlan.

She once had the biggest following of any woman on Vine, while Tommy's had the biggest ... popularity among rock drummers.

Good to see Tommy's still living by his motto: Live long and prosper.
