Chelsea and Jon were introduced back in 2011, according to Hollywood.com by a mutual friend and Divergent star, Zoe Kravitz.

Together, they are the producers of the band BadBad, according to Us Weekly, an electronic soul group that formed in 2013.

Chelsea and Jon spoke to Teen Vogue back in 2013 about their music.

“We have two simple goals: to make you feel and to make you move,” Chelsea said.

Jon added: “There’s no bigger reward than making people dance their cares away.”

Chelsea, who’s real name is Chelsea Anna Tallarico, is the daughter of Teresa Barrick. She has one brother, Taj Tallarico, from the same mother, a half-sister, Mia (her mother is Cyrinda Foxe) and actress Liv Tyler (whose mom is singer Bebe Buell).

Jon Foster is the younger brother to actor Ben Foster, who stars in Lone Survivor.
