[article id="1673747"]Justin Bieber recently told the "Today" show[/article] that it's impossible he fathered Mariah Yeater's baby, as claimed in a headline-making [article id="1673599"]paternity suit[/article]. Why? The minute he finishes a show, he promptly makes his way from the stage to an awaiting car, so there's no time for backstage trysts.

Cobra Starship frontman Gabe Saporta, [article id="1672051"]Bieber's onetime tourmate[/article], confirmed the teen star's story.

"It wouldn't even be possible for her to get backstage," he told MTV News on the red carpet at the [article id="1673947"]Glamour Women of the Year event[/article] in New York on Monday. "The security is so crazy there, you can't get backstage. And even if you got backstage, first of all, he leaves the show as soon as he's offstage, which is pretty cool. He runs offstage, gets in a car and jets, because the whole city turns into chaos."

Before the My World Tour wrapped up last month, the band experienced that craziness firsthand, likening it to something straight out of the movies. "There's a really cool video of us online getting mobbed at the airport," Saporta recalled. "It's like zombie apocalypse; it's awesome."

Speaking of awesome, 2011 has been a pretty great year for Cobra Starship. Their infectious, Sabi-featuring track "You Make Me Feel" has been burning up radio, but that Bieber tour is pretty much the highlight of the year for Saporta.

"We were playing, like, 50,000-people stadiums," Saporta said of the South American jaunt. "It was insane, and I'm from South America too, so for me, it was especially satisfying. I gotta say, for being the most famous kid in the universe, he's remarkably well-adjusted, and ... there's like 75 people traveling with him. It feels like a family, and it was really nice to be a part of that family for a bit of time."
