And the four-time Grammy winner appears to have since become best bros with Lisa's current husband Jason Momoa.
He even wished his buddy a happy 41st birthday Saturday, as he took to Instagram with a black-and-white snapshot and a sweet tribute to the birthday boy.
The 56-year-old captioned the unapologetically iconic photo: 'Happy Birthday @prideofgypsies. One family. One love.'
He later responded to one of his 3.2million followers, who admired their friendship, which she noted 'probably wasnt/isnt always easy.'
The American Woman artist replied to the comment: 'Easy and beautiful from the first moment. Blessed !'
He and Bonet, 52, were married in 1987, and they 'amicably divorced' in 1993, long before conscious uncoupling started trending.
Momoa later tied the knot with Bonet in 2017, becoming stepfather to actress Zoë Kravitz, 31.
The Big Little Lies actress also wished her stepdad a happy birthday, writing on Instagram: 'happy birthday papabear! i love you.'
She shared a sweet Polaroid of herself hugging the Aquaman star, who towers over her 5ft, 2in frame at 6ft, 4in.
Zoë recently joined her 'papabear' in the DC universe, when she was cast alongside Robert Pattinson's Dark Knight as Catwoman in The Batman.
Momoa and Bonet also share daughter Lola Iolani, 13, and son Nakoa-Wolf Manakauapo Namakaeha, 11.
