Klay Thompson says he is NOT DATING the L.A. Rams cheerleader who tagged her name on the NBA star's patio ... she's just a friend ... of a friend.
Social media blew up this week after Cherise Sandra posted a picture of herself outside Klay's house. The pic -- and the caption ("You & Me Baby") -- led some people to believe the two had a thing.
But it just AIN'T TRUE, according to Klay's rep, who tells us, "They aren't dating at all. The first time they met was that day. She was a guest of a guest, that's it."
As for Cherise's name in graffiti ... sources at the party tell us Klay was cool with the girls tagging the patio ... but only 'cause it's about to be renovated.
Rest easy, ladies.
