One Direction mania is live and in full effect, and the guys are well prepared for it. They amassed a massive security team for their Dallas, Texas concert yesterday (March 24).

TMZ reports that the 'X Factor U.K.' alumni had a whopping 100 security guards on hand for their show, which only consisted of a four-song, 45-minute set at the Dr. Pepper Ballpark. To keep the 'One Thing' singers safe from the 7,000 Directioners, 40 guards were hired for close protection security, 50 for the venue and 10 extra just in case. It may sound like a bit much, but also bear in mind that security guards also keep the crowds, not just the artists, safe.

From the sounds of it, though, the guards were warranted. When the band performed in Toronto, so many fans flooded the area that entire streets were shut down. This may also serve as a trial run for their upcoming North American tour.

One Direction aren't the only U.K. imports to need some extra help keeping screaming girls at bay. Friendly (or not?) rivals the Wanted recently had the stage shut down at their taping of mtvU's Spring Break when fans bumrushed the stage.

In any case, better safe than sorry -- we'd hate to see anything happen to any of our boys!
