The 20-year-old 'Hannah Montana' star has replaced supermodel Bar Refaeli as the hottest female celebrity making in a poll by Maxim magazine.
Cyrus took a huge leap from her last year's position at 68th spot.
Though the magazine hasn't revealed the annual list for the world's most beautiful celebs that usually comes with a special issue. But Cyrus broke the news on Twitter.
"Didn't know this was coming out yet! I'm so happy to be 1 on Maxims HOT 100! dreams do come true (sic)," Cyrus tweeted along with a picture of her taken from the inside spread of the upcoming edition of the magazine.
