In 2008, Drew was a guest star in The Suite Life Of Zack and Cody as the grandson of a guy who lost his phone and was later found by Maddie. He also made an appearance in Stuck In The Suburbs in 2004 as the hotel clerk. He was later cast in Another Cinderella Story for Warner Bros. with Selena Gomez. It was released on September 16th. There has been controversy over Drew and Selena's kiss in the movie due to the fact that he is 26 and she is 16. But despite all the controversy, it has been made very clear that Selena and Drew's relationship is nothing more than friendship and respect for one another. The 13 track CD for the movie with hit song "Tell Me Something I Don't Know" was made available in August.
Drew has just finished filming the lead role of Derek in The Shortcut, a thriller/horror by Adam Sandler's "Scary Madison Productions" which will be out early in 2009.
