When Elvis Duran and the Morning Show team hosted One Direction at the Z-100 studios last Friday, things got a little messy.

After the interview segment, which focused on the group's No. 1 album Up All Night and U.S. tour (and, of course, the usual Elvis-style banter) 1D was treated to a sweet snack provided by Cold Stone Creamery: An ice cream cake decorated with a British flag. Just as they were about to dig in, 1D members Zayn Malik and Louis Tomlinson had a characteristicly silly moment and pushed fellow member Harry Styles' face right into the cake!

Without missing a beat, Styles continued to pose for photos with bandmates and Elvis team members. He even planted an unexpected smooch on Elvis radio team member Carolina Bermudez, cake-faced and all.

The incident reflected the group's attitude toward fame: Work hard, but find fun in every situation you can. "These guys went from zero to sixty overnight," Duran said after the segment. "This was not a four to five-year investment. It was like, [ X Factor], the album, touring, bam." When asked if history was repeating itself with the boy band mania of the late '90s and early 2000s, Duran noted that the Internet and social media are largely responsible for 1D's rapid rise to stardom.

"Ten years ago, those bands didn't have the tools that are available now," Duran said. "When One Direction opened for Big Time Rush, no one expected how huge they'd be. People were singing every word to hidden tracks."

According to Duran, "the music is solid and the boys blend well together. People are in line to work with them."

A dream collborator for the group is Bruno Mars, whom they all agreed upon unanimously.

"He's got everything - he's got the stage presence, he's got a great voice, he looks great," said group member Louis Tomlinsion during the interview.

As they gear up for a performance on "Satruday Night Live" airing April 7, the boys are mostly looking forward to meeting that night's host, Sofia Vergara.

"And that lady from Bridesmaids, Kristen Wiig is it?" Styles quipped.

Duran, whose radio voice was suffering due to allergies, has been busy with charity work, including Rosie O'Donnell's Theater Kids program; he serves on its board of directors. The organization works with at-risk students in Manhattan, teaching them the basics of stage performance, funding scholarships, and trips to Broadway shows.
