Disney Channel star Brenda Song is expecting her first child with her boyfriend, Miley Cyrus‘s older half-brother, Trace Cyrus. Song, 23, gained stardom with the pre-teen set when she was cast as loopy heiress London Tipton on Disney’s The Suite Life of Zack and Cody in 2005. She and Trace first went public as a couple in May 2010. The heavily tattooed Trace, 22, whose birth name is Neil Timothy Helson, previously dated Disney’s Sonny with a Chance star Demi Lovato but they broke up in 2009. His parents divorced when he was four, and he legally changed his name to Trace Dempsey Cyrus when he and his sister Brandi were adopted by Billy Ray Cyrus after the country singer married their mother Tish.
