Katy Perry is on top of the world! She has a hit song, a brand-new album and has met the love of her life! Things are definitely looking up for the star who divorced from Russell Brand after 14 months of marriage in 2011.

On Tuesday night, the "California Gurls" singer wowed the crowd at a performance celebrating the release of her highly anticipated album, Prism, at the opening of the iHeartRadio Theater in Burbank.

The about-to-be 29-year-old rocked the stage with her hit song "Roar." For the fun-filled night, Katy wore a silver leotard under a see-through dress, fishnet stockings and white platform heels. During the number, Katy was flanked by two back-up singers in all white and and a four-piece band, who were also in all white.

Tuesday night's event also included an interview with the singer, and during the interview the brunette beauty admitted to something a bit odd!

Apparently, the "Last Friday Night" singer keeps the tresses from two other famous songstresses as a memento from her first ever appearance at the Grammy Awards.

The 28-year-old said: "One of the first times I went to the Grammys, I got to share a dressing room with Miley Cyrus and Taylor Swift and I asked them for a lock of their hair from each one of them, which is totally creepy, but awesome."

She continued, "I put little bows on them individually and put them in my purse. And that was my little secret - I'm a freak!"

The sexy singer has been doing a lot of opening up these days. In a recent interview with W magazine, the singer admitted she had the hots for boyfriend John Mayer, 36, well before they hooked up in 2012.

In the interview, when asked if she had any movie star crushes, Katy admitted, "I actually am dating my crush. I had a crush on him for a long time, and it just so happens we fit together great."

Aww too cute! We love that things are going so well for Katy. And we having a feeling more good news is coming her way -- we keep hearing that her "Wonderland" singer will be popping the question any day now!
