Justin Guarini Claims He Hooked Up with Both Kelly Clarkson and Tamyra Gray Back in His "American Idol" Days

Remember JUSTIN GUARINI, the guy who lost to KELLY CLARKSON on the first season of "American Idol"?  Well, he's married with kids now, but he's claiming he was quite the playboy back in his "Idol" days.


At a recent performance of his one-man stage show, "Lovesick", Justin told the crowd that he and Kelly started hooking up while they were filming their horrible post-"Idol" movie, "From Justin to Kelly".


He didn't say how long they were together, but it was short-lived.  He basically said he was left behind when Kelly's career started taking off, and his didn't.


But Kelly wasn't Justin's only conquest.  Supposedly, he also had a "fling" with TAMYRA GRAY, who came in fourth that season.


Kelly hasn't responded, so it's unclear if she remembers who Justin is.
