Katy Perry's 10 Biggest Billboard Hits

Before "Roar" gets added to the pop star's list of hits, take a look back at Katy's most successful singles to date.

On Monday (Aug. 12), Katy Perry will return with "Roar," the first single from her highly anticipated third studio album "Prism." The 28-year-old has announced through a series of teaser videos that she's ready to move on to the next phase of her musical career… but before she does, it's worth noting just how staggering her solo career has been ever since she admitted to kissing a girl in her debut single in 2008. Over two albums (plus a "Complete Confection" deluxe edition of her sophomore LP), Perry has notched a whopping seven No. 1 singles on the Hot 100 chart, including five chart-toppers from her "Teenage Dream" album, which tied a record set by Michael Jackson with his "Bad" full-length. From the inspirational "Firework" to the defiant "Part of Me" to the salacious "I Kissed a Girl," Perry proved her staying power in pop music long before announcing that she was coming back with a "Roar."

10. PART OF ME
Hot 100 Peak Position: No. 1 (1 week)
March 3, 2012



The first single from last year's "Teenage Dream: The Complete Confection" re-release, "Part of Me" allowed Perry to purge herself of lingering emotion following a painful breakup, and defiantly reclaim her independence. After "Teenage Dream" produced five No. 1 singles, "Part of Me" added yet another to the singer's resume.

9. THE ONE THAT GOT AWAY
Hot 100 Peak Position: No. 3
January 7, 2012



"The One That Got Away" lived up to its name on the Hot 100 chart -- after releasing five No. 1 singles from "Teenage Dream" and watching them all streak to the top of the chart, Perry guided the album's sixth single to a tantalizing No. 3 peak before it sadly fell back down the tally. Still, "One" proved to be another monster hit for the singer, sporting a more wistful shade when compared to her other "Teenage Dream" fare.

8. WIDE AWAKE
Hot 100 Peak Position: No. 2
August 11, 2012



Perry's most recent hit, "Wide Awake" almost joined its predecessor "Part of Me" as a No. 1 hit from "Complete Confection" but tapped out in the runner-up spot. Produced by Dr. Luke and Cirkut and debuted at the 2012 Billboard Music Awards, "Wide Awake" is a soaring, contemplative ode to falling away from romance and finding the clarity and strength to soldier on.

7. LAST FRIDAY NIGHT (T.G.I.F.)
Hot 100 Peak Position: No. 1 (2 weeks)
August 27, 2011



Pink flamingos! Maxed-out credit cards! Skinny dipping! Last Friday night was particularly crazy for Katy, and "Last Friday Night" was another smash, serving as the single that let "Teenage Dream" tie "Bad's" record of five No. 1 singles. The song's music video featured cameos by Darren Criss, Rebecca Black and Kenny G (among others), and a remix of the track added a verse by Missy Elliott.

6. TEENAGE DREAM
Hot 100 Peak Position: No. 1 (2 weeks)
September 18, 2010



If "California Gurls" was the single that cemented Perry as a hitmaker ahead of her second album release, "Teenage Dream's" title track demonstrated the pop star's versatility. With a slower tempo and more thoughtful lyrics about the joy of carefree love, "Teenage Dream" was a change-up that earned critical raves and another avalanche of radio success.


5. HOT N COLD
Hot 100 Peak Position: No. 3
November 22, 2008



For those who thought Perry would be a one-hit wonder and fade into obscurity following "I Kissed a Girl," "Hot N Cold" was a decisive blow to their dismissive theories. Not many pop performers would use the line "You PMS like a bitch I would know" in the opening verse of a hook-filled anthem, but then again, not many pop performers take Katy Perry's risks.

4. I KISSED A GIRL
Hot 100 Peak Position: No. 1 (7 weeks)
July 5, 2008



And then, of course, there's the song that started it all. "I Kissed a Girl" was both the 2008 Song of the Summer and the official arrival of Perry as a solo artist, bringing its bi-curious electro-pop to the top of the Hot 100 tally for seven weeks in 2008. "One Of The Boys," Perry's debut solo album, would go on to sell 1.5 million copies after "I Kissed a Girl's" introduction, according to Nielsen SoundScan.

3. CALIFORNIA GURLS
Hot 100 Peak Position: No. 1 (6 weeks)
June 19, 2010



"One Of The Boys" helped make Perry a household name, and for the first single for the follow-up album, the singer had to make a splash. She recruited Snoop Dogg, heralded the women of California and unsurprisingly scored. "California Gurls" was the song of the summer in 2010 and will forever be on rotation at summer beach parties.

2. FIREWORK
Hot 100 Peak Position: No. 1 (4 weeks)
December 18, 2010



The third single (and third No. 1) from "Teenage Dream" was a collaboration with production duo Stargate that allowed Perry project her lyrical power outward and inspire her millions of KatyCats. The music video, which showed others embracing their confidence as the chorus exploded, eventually won Video of the Year at the 2011 MTV Video Music Awards.

1. E.T.
Hot 100 Peak Position: No. 1 (5 weeks)
April 9, 2011



Katy Perry's biggest Billboard hit to date is also one of Kanye West's biggest chart hits ever, as the single ruled the Hot 100 with its stuttering beat and tale of indulging in the unknown for over a month. "You're not like the others," Perry sighed on the track, and she was right -- "E.T." stands on its own within her deep catalog of hits.
