Randy Couture and his wife have a message for their friend Demi Lovato -- "We love Demi and we're going to do whatever we can to help."
Couture has been helping Lovato train at Jay Glazer's Unbreakable gym in West Hollywood for years -- she's even credited him with helping her achieve her blue belt in Brazilian Jiu-Jitsu.
Randy says everyone in the gym has been well aware of her struggles with addiction -- and he was crushed to hear about her overdose on Tuesday.
But Couture says the singer can count on his support and love as she begins to bounce back.
