Twilight co-stars Robert Pattinson and Kristen Stewart have fueled rumors they're dating in secret after they were snapped kissing at a concert in Canada.

A crafty fan grabbed a snap of the pair smooching in the audience at a Kings of Leon gig in Vancouver on Saturday night.

It comes just days after actress Jennie Garth revealed Pattinson was dating an un-named castmember - gossip she'd obtained from her "Twilight"-starring husband Peter Facinelli.

She told the New York Daily News, "I can't say (who it is), because that would be breaking my promise (to husband Facinelli), but he (Pattinson) is dating one of them."
