The High School Musical star Zac Efron is known to be a bit of a lady killer. Just look at his insanely hot jaw line, his smile, his hair and of course, and he doesn't have a bad bone in his body. Remember, when he flew all the way to Rio to surprise the United States girls gymnastics team because they loved him so much?!

So, whose heart – besides the millions of fans and the U.S. gymnasts that wish they could date him – did he break? And no, it wasn't Vanessa Hudgens.

It was actually Paris Jackson! She made an appearance on The Tonight Show and revealed that her first concert was the High School Musical tour. Unbeknownst to her, Zac wasn't on the tour and that totally broke her heart. It seems like she's still torn up about it and to be honest, we don't blame her!

She said, "The first concert I actively really wanted to see was High School Musical Live. [Efron] actually wasn't there. I was so bummed. He wasn't there."

Paris said that Zac was filming a movie with horses at the time which is why he couldn't make it. The movie we believe she is referring to is The Derby Stallion which came out in 2005. The High School Musical concert tour started in 2006 so it doesn't seem like he could have possibly been filming at the time. According to reports, he was actually filming Hairspray. BUT, that's beside the fact. The point is, Zac wasn't there and it was a huge deal for Paris.

She continued, "They had some guy replace him [on the tour]. That was the most depressing part about it. He wasn't there, and I was, like, this heartbroken 10-year-old." Aww!

This is actually super sad but so cute. Zac was every girl's dream guy when High School Musical was in its prime on Disney Channel so we have a feeling more hearts were broken on that tour than just Paris' when fans realized Zac was nowhere to be found.

However, when Zac hears things like this, he is known to respond. Our fingers are crossed that Paris gets some sort of shoutout from her old crush!
