"Rock Star in the House" is the 19th episode of the first season of The Suite Life of Karan & Kabir. Zafar Ali checks into the Raj Mahal Hotel and Vinnie, Rani, and Karan break into Zafar's room. Karan collects discarded items belonging to Zafar, so he could sell them. Kabir enters a science fair, and receives help from Digital.
Zafar Ali comes to the Raj Mahal Hotel. Rani tries to meet him. Although at first Vinnie only wants to meet him for journalistic reasons, soon she has a crush on Zafar too. So, they do some really stupid things, such as dress up as waiters and sneak into his hotel room through the balcony. Karan attempts to find items that Zafar leaves around the room and sells them on the street. Karan steals Zafar's lucky bracelet, but Vinnie and Rani tell him that he has to return it or "he could freeze up in the middle of his concert and we'd be responsible for ruining his career". While returning his lucky bracelet, they wake up Zafar, and Karan is almost taken away by security while Vinnie and Rani escape through the balcony. When Zafar finds out that Vinnie and Rani are five years older than Karan, he tells security to let go of him. The episode ends with Zafar and Karan playing video games.
Meanwhile, Kabir wants to win an award at the Science Fair, but when he sees he didn't do it too well, he calls on Digital to help him. However, it was against the rules because Digital did all the work, and he didn't do anything.
In the Science Fair, he wins, but then confesses that he got help, and the prize was for another child.
