This week we get NSYNC with Ross' Mom and Lance Bass (*NSYNC, Dirty Pop with Lance Bass, Lance Loves Michael). Lance covers everything - from boy band days, to Britney to Cosmonaut training, and even the backlash he faced coming out. He finishes by launching a duet with Ross' starry-eyed assistant Brandon. Plus there's another scintillating round of Are You Smarter than Mark. And Ross caps it all off by probing Mark to learn that he's definitely "less than seven."
