[article id="1598710"]Lance Bass[/article] cannot believe he is one of the four remaining celebrities in the running to win the seventh season of ABC's "Dancing With the Stars." Sure, he spent a good part of his early career dancing in 'NSYNC, but Bass insists that his previous training didn't give him an advantage on the show.

"I can't believe we're still standing, but everyone is so good this season. These next few weeks are going to be insane," he told MTV News during rehearsals with his partner, "So You Think You Can Dance" alumna Lacey Schwimmer. "These judges are so wishy-washy. ... This season they're really hard-core, but I think it's to bump you to the next level. They're just pushing us to be better.

"My 'NSYNC training has not helped me at all for 'DWTS,' " Bass declared, though he's following in the footsteps of other ex-boy-banders turned accomplished "DWTS" contestants Drew Lachey, Joey McIntyre and Joey Fatone. "With 'NSYNC -- I was going to say, 'It's all hip-hop,' [though] it didn't look like hip-hop. I've had a lot of hip-hop training, but with ballroom, it's more posture and lines. ... I'm more ghetto, and ballroom is more vanilla. I've had to learn how to be vanilla."

[article id="1457381"]Bass also did some training to go into space[/article], before his mission failed in 2002. Did any of that come in handy for the dance competition? "I don't know how much it helped me for 'DWTS,' " he said. "The physical training has definitely helped me, 'cause I'm used to all the cardio that we're doing, but we put in crazy hours in the studio."

Of course, Bass has also gotten some help from his 'NSYNC pal Fatone, who competed in the fourth season of "DWTS." "Joey has given me some good advice. I'll take all the advice I can get. I usually don't listen to Joey," he joked, "but in this case, I do. He came in second place, so he's one you listen to."

At the end of the day, though, Bass is continually surprised by the accomplishments he's making as a dancer on the show. And, he's not ashamed to admit it. "I watch on TiVo, and I think, 'Who is that guy?' " he said. "I'm impressed with myself, 'cause for that one moment, I looked damn good."
