"The Lucky One" star Zac Efron ignites the May cover of "Men's Health" with his incredibly muscular arms.

Zac and "The Lucky One" co-star Taylor Schilling sat down with "Extra's" Ben Lyons to talk about filming the steamy love scenes for their new movie. Also, Zac talks about bulking up for the role, which included 5 months of training with a former Navy SEAL!

"The Lorax" star Zac Efron made on an appearance on the "Today" on Thursday to talk about his animated movie, but host Matt Lauer wasted no time in asking the 24-year-old actor about the caught-on-tape moment when a prophylactic dropped out of Efron's pocket at the premiere.

Watch the awkward exchange!

Carpet antics aside, Efron said he was thrilled to play the lead male role of Ted in "The Lorax" -- a 12-year-old boy who pines for an older girl, Audrey, voiced by Taylor Swift, particularly since Theodor Geisel's (aka Dr. Seuss) widow sent him a letter specifically asking him to take on the role.
