- Follow Us! Things are heating up on the set of Nick's "True Jackson,VP." Who's making a guest appearance on the show? Watch and learn! Hey Guys-I'm Joslyn Davis for ClevverTV. Teen superstar Justin Bieber is confirming an appearance on "True Jackson, VP" coming up next month. The "One Time" singer will appear on the show as himself, where he'll sing his big hit for a charity concert within the episode. "True Jackson, VP" stars Keke Palmer, who in case you didn't arleady know, is quite the singer herself. Justin tweeted out that he was on the set of the show in LA and that Keke is really cool. He then added that she (and I quote) "might sing 'One Time' with me as a duet." I hope he's not kidding with this one because that would be amazing! What do you guys think of the possible duet?
