One Direction, Simon Cowell's British boy band, is heating up. The band's popularity is skyrocketing as the boys gain more and more fans worldwide. The five boys -- Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - are quickly becoming heartthrobs with their breakout hit, What Makes You Beautiful. But with fame often comes troubles and One Direction has already had a few.

TMZ reported on Friday that on April 4, during their Saturday Night Live rehearsal, One Direction was afraid of a run-in with fellow boy band, The Wanted.

One Direction was rehearsing for SNL at CenterStaging in Burbank, Calif., when security was notified that The Wanted was about to show up to the very same studio to rehearse for an American Idol performance.

TMZ was told by sources connected to CenterStaging that the boys from One Direction, all except Liam, were scared. British tabloids have been writing about tension and smack talk between the 2 bands. The One Direction lads talked about the guys from The Wanted being tough guys (which apparently is true) and they were worried about getting taunted and manhandled, reported TMZ.

Security guards for the two bands supposedly talked about One Direction's fears, as One Direction was attempting to wrap up the rehearsal. But when Max of The Wanted heard of One Direction's misgivings, he ran into the studio and gave Liam a big hug.

Everyone supposedly laughed about it, except for Louis who supposedly refused to go near the rival boy band.

This is not the only snafu One Direction has faced as of late.

The band was sued on April 10 for trademark infringement, reported Reuters, because it is using the same name as a lesser-known California pop-rock group.

Attorneys for the California band are reportedly seeking an injunction that would stop Cowell's One Direction from using the name in promotional materials along with a share of the profits earned by the budding stars. The California band claims it is entitled to three times the profits made by their rivals, as well as compensatory damages in excess of $1 million, reported Reuters.

Despite these minute troubles, One Direction shows no sign of slowing down.

The band had to decline an invitation from Michelle Obama to perform at the White House's annual Easter Egg Roll on Easter Monday due to prior commitments. The band did meet with the First Lady and reportedly joked about how the First Family orders pizza at the White House, according to Huffington Post.

Coping with fame might prove stressful. Other famous band members know what it is like having to deal with swift, astronomical success like One Direction is currently experiencing.

Former Beatles member Paul McCartney said, There are so many bands who all get called 'the next Beatles'. Suddenly it puts an awful lot of pressure on them to be the next Beatles. He told ITV1's Daybreak, Oasis were 'the next Beatles' once, if you remember. It's a pressure, because suddenly you've got to live up to all the things that we did, and it was a different time. So let's just call them 'the next terrific band' he said, wishing them good luck.
