The two ladies posed for a photo on Instagram recently, and Cabello shared how proud she was this Harmonizer chose "Camila" as her new name.

The stunning, confident, magical woman standing next to me is named Camila Joe. I met her during a signing last year when her name was "Joey" and she told me I inspired her to have the courage to transition.

Right before my eyes, today I saw a beautiful, confident woman (with IMMACULATE EYELINER by the way). She told me she was going to go by the name of Camila Joe and I kinda lost it with excitement. I don't know your Twitter but I just wanted to say how proud I am of you.

There's a light in someone's eyes when they become who they want to be. Today you lit up the whole room. i love you darlin. WORK THAT POSE.

That's pretty darn "BO$$" if you ask us.
