Dancing with the Stars' Mark Ballas Is Engaged

Dancing with the Stars pro Mark Ballas is engaged to his longtime girlfriend and bandmate, singer/songwriter BC Jean, Us Weeklyreports.

Ballas, 29, reportedly popped the question to Jean, 28, in November just before Thanksgiving. "They have been keeping their exciting news on the down-low as they wanted to celebrate and enjoy the holidays with close friends and family," a source tells Us.

Ballas and Jean, who penned Beyonce's song "If I Were a Boy," have been dating since 2012 and formed the group Alexander Jean. Their song "Roses and Violets" was featured on the most recent season of Dancing with the Stars, for a routine that champs Derek Hough and Bindi Irwin performed together. The group is also scheduled to perform at the SXSW festival in Austin, Texas, in March.
