Things got pretty steamy between Glee
stars John Stamos, Naya Rivera and Cory Monteith
Saturday night – on stage at the GLAAD awards, that is.
It all started when Rivera, who was co-hosting the 23rd Annual GLAAD Media Awards in New York along with Monteith, announced she would sell her "sweet lady kisses to the highest bidder" to help raise funds.
Monteith wasn't going to let the offer go unchallenged, offering his own smooching services – complete with freshly applied ChapStick – to interested bidders.
A sporting Monteith told the audience, which was in attendance to support gay and lesbian issues, "I have kissed Naya and it is fricken' awesome," but Rivera had fighting words: "It's officially a kiss-off," she announced, between "my juicy lips and his thin ones."
As the auction heated up and went into the thousands of dollars, a surprise suitor popped up: One of the night's presenters, John Stamos, bid for Monteith's services. As the crowd whooped and cheered, the bidding for a kiss with Monteith went higher, until Stamos had an even better idea: He decided to jump on stage and offer himself up for bidding. All three stars quickly drew a price of $5,000 each.
As Rivera greeted the man who won her in the auction and Monteith greeted his winner, Smash star Megan Hilty
, Stamos met his bidder, a strapping male.
To more laughter from the audience, Stamos joked to the man, "I got the better prize. Come to daddy!" before all three stars all had a quick kiss, with Rivera's bidder dipping her for a romantic smooch, as the audience roared.
Rivera is certainly enjoying her single life. She tells PEOPLE exclusively she's currently not serious with anyone, but isn't sitting home worrying about it: "I say this all the time: I'm always dating. I'm 25 and so of course I'm going out and trying to hang out with cute boys."
