Zac Efron is the ultimate bra-removal expert!

While promoting The Lucky One, Efron recently revealed a secret, naughty talent when he was asked in a recent interview to demonstrate how he unhooked his co-star Taylor Schilling's bra with one hand in the new romantic film. Since that funny demo, the 24-year-old heartthrob has made a name for himself.

On Jimmy Kimmel Live Monday night, the host decided to put Efron's skills to the test -- challenging him to a bra unhooking contest, employing two men from his security team. Kimmel's guards were each wearing five bras, and Efron and Kimmel raced each other in unhooking them from the front.


"You're a little bigger than most of the girls I've done this on," Efron told the burly guard wearing multiple bras.

The actor had to use two hands to get the job done, but still defended his title as bra-removal king -- handily beating Kimmel in the contest.

The Lucky One opens in theaters Friday.
