Is Harry Styles cheating on rumored girlfriend Kendall Jenner already? One Direction heartthrob spotted flirting with mystery brunette at Sundance party

So we're still not sure if Harry Styles and Kendall Jenner are officially dating (though it definitely seems like they are), but it looks like the One Direction hunk was canoodling with another sexy brunette earlier this week! According to some eyewitnesses, the "Story of My Life" singer was spotted flirting with a mystery lady at a Sundance party celebrating Zach Braff's new movie Wish I Was Here. Though we don't know who the lucky girl is that had Harry's attention, we do know it was not his rumored girlfriend Kendall Jenner!

"Harry came to the party with a group of people, he was with three guys and two girls-one of the girls was a brunette and one was a blonde," a source revealed. "They were all sitting together in a corner booth laughing and having a good time."

Of course, just "laughing" isn't much of a crime, nor is "having a good time." No, what really stirred the rumor mill was that this eyewitness says that Harry was actually flirting all night with the girl, apparently forgetting about his recent PDA session with Kendall Jenner at a Los Angeles concert.

"As the night went on, I could see Harry flirting with the brunette," the insider went on. "At one point it was just the two of them canoodling in the corner...they were really into each other."

"Canoodling" is definitely a heavy-handed word these days, so we shouldn't jump to any conclusions. Do you think Harry was cheating on Kendall or was he just having a good time without any infidelity involved? Does it even matter though, considering he and Kendall have yet to officially confirm this rumored relationship?
