In 2005, Song began appearing in the role of spoiled heiress London Tipton in the Disney Channel Original Series, "The Suite Life of Zack & Cody". The role was named "Paris" in an early script and alludes to Paris Hilton (London spoofing Paris, and Tipton is the name of the hotel her father owns in the show). She got the role without an audition and was surprised to find her friend Ashley Tisdale working in the show. Song says, "London is my fantasy person, I wish I could be her. I wish I had her closet."
