Mandy Moore dating Ryan Adams

Hollywood good girl Mandy Moore is the latest celebrity to be dating grungy rocker Ryan Adams, according to U.S. reports.

"Ryan and Mandy have been dating for months," an insider told InTouch magazine.

Ryan has previously dated a string of glamorous actresses, most famously Winona Ryder and Parker Posey. But he has not been seen much with Mandy because friends say he hates all the attention.

"He hates all of the Hollywood type stuff or being photographed," the insider said.

Mandy, too, has been secretive, last month telling a magazine reporter she was "a single girl" even though InTouch insists she has been seeing Ryan since December

But she gave some heavy hints, saying: "He has t be musically inclined or involved or obsessed."
