Paris Jackson revealed a lot of her firsts in her initial appearance at "The Tonight Show" on NBC on Monday. From her first concert experience to her first broken heart, the only daughter of Michael Jackson bared it all to the show's host Jimmy Fallon.

Paris unveiled that the first real show that she graced was "High School Musical Live." Fallon, on the other hand, gushed saying the name of Zac Efron. "He actually wasn't there. I was so bummed! He wasn't there, he was filming that movie with horses," she regretfully said.

The 18-year-old star then revealed that Efron was replaced by Drew Seeley and that actually depressed her. The fact that Paris didn't see the 29-year-old hunk that time made her the 10-year-old young brokenhearted girl.

And although she didn't get starstruck with Efron, Paris' heart jumped when she saw Alice Cooper in person. While playing with Deb and Butch Walker for the Halloween, the television personality excitedly shared that she met him backstage.

"I was telling him 'I love you so much. I always listened to you. I grew up, like, loving you...' and I was close to tears," Paris narrated. Fallon then teased her that she looked like she was about to cry.

Although Fallon felt a little weird that time, Paris went on to say that Cooper was really nice and even called him a "total bae." However, the unfamiliar word made "The Tonight Show" host felt "so old."

Meanwhile, other firsts that Paris told Fallon were her first vinyl, which was the 1967 album of The Beatles, "Sgt. Pepper's Lonely Hearts Club Band." Also, her first CD was "The Lion King" soundtrack.

The first time that she attended a concert was her father Michael's "Invincible Tour" in 2001. And for her appearance on "The Tonight Show," she played the Egg Russian Roulette with Fallon.
