Shenae Grimes Finds John Mayer Dating Rumors ‘Embarrassing’

Shanae Grimes not only denies dating John Mayer, but even managed to bruise the celebrity serial dater’s ego too!

“According to Star magazine John Mayer and I are in secret sexy cahoots,” Grimes (pictured filming her role as a homeless teenager on the set of Sugar in Los Angeles) tweeted yesterday. “How wonderful for me…if wonderful meant embarrassing.” Ouch. Looks like Mayer has experienced a very different kind of napalm attack from the 90210 star.

Mayer’s camp is keeping mum.

“They are not dating,” a close source said, followed by the singer’s rep who added, “Star magazine is not a credible source.” I think a 21-year-old B-list celebrity calling the mere idea of going on a date with you embarrassing is credible enough for now. Case closed.
