Adam Duritz of Counting Crows perform at 2008 T in the Park music festival - Day 3, Perth and Kinross, Scotland - 13.07.08

The Mr. Jones singer, who has romanced Courteney Cox and Jennifer Aniston in the past, is dating Avenue Q star Mary Faber.

A source tells In Touch magazine, "They've been dating a couple of months."

And Duritz is so smitten with his new love, he even changed the lyrics of Counting Crows' All I Need is You during a recent Wantagh, New York concert to pay tribute to Faber.
