Jenn Brown: Kenny Chesney's Alleged ESPN Mistress (PHOTOS)

Star Magazine is reporting that country star Kenny Chesney is cheating on his girlfriend with ESPN reporter Jenn Brown.

The magazine has what it says are photos of the pair on the beach together in Mexico.

"They were touching and rubbing each other the whole time," an eyewitness told Star. "They definitely looked like lovers, like they didn't have a care in the world."

The August 30 issue of Star hits newsstands this week.
