Richie Sambora is smitten with his new girlfriend, who's almost half his age!

The former Bon Jovi guitarist was spotted locking lips with his much younger love, fellow guitarist Orianthi, at the Breeders Cup in Los Angeles over the weekend.

The Rock n' Roll duo have been dating since last January, and it seems like the musicians still can't get enough of each other. Before watching the race, the pair took the stage together at the event and looked like they had a great time performing for the crowd.

Orianthi, who toured with Alice Cooper over the summer, is also planning to hit the studio soon with Sambora. Reportedly, the couple is working on a new album together.

The 55-year-old was previously married to Heather Locklear until 2007, and split from Denise Richards in 2012.
