Trace Cyrus, the rocker older brother of Miley Cyrus, is expecting a child with Disney actress Brenda Song, MTV News reported Wednesday. It will be the first child for both Cyrus, 22, and Song, 23, who began dating in May 2010. Before the pair hooked up, they had been linked to fellow members of the Disney dynasty. Cyrus dated former "Sonny with a Chance" star Demi Lovato in 2009 and Song had been romanced by singer Joe Jonas in 2008.
