Sometimes a friendship blossoms into romance.  That's the story behind Sheryl Crow's new romance. 

She is dating musician Doyle Bramhall II, who plays in her band and also co-produced Sheryl's latest album, "100 Miles from Memphis."  People.com reports that Sjheryl has been friends with Doyle for about fifteen years and that only recently did their friendship turn into a romance.  A source tells People.com that Doyle is a great guy and Sheryl is really happy.  Sheryl recently told "Prevention" magazine that she's pretty careful with relationships around her kids.  She said, "We have a great foundation, having known each other for fifteen years.  I've been in the situation where I've been involved with people and their kids, and if the relationship doesn't work out, it's heartbreak.  So I'm keeping the relationship friend-based when we're around the kids."  Sheryl has two sons, ages three and one.
