Joe’s closest friends and family also have ties to boxing, with his younger brother, Nick Jonas, appearing in the MMA fighter drama, Kingdom, for three seasons and his ex-girlfriend and longtime pal, Demi Lovato, is currently dating MMA fighter Guilherme “Bomba” Vasconcelos. Joe has been training with Ava Knight – a noteworthy female boxer – for several months now. He was spotted practicing with Knight outdoors back in September.
