• Lenny Kravitz shared on Instagram a photo of himself and Jason Momoa Monday to mark the latter's birthday
  • The singer wished the "Aquaman" star "love" on his 43rd birthday 
  • Momoa responded to Kravitz's sweet tribute, commenting, "love [you] forever"

Lenny Kravitz gave Jason Momoa a special shoutout on his birthday.

Lisa Bonet's exes proved that their bromance is going strong when the "It Ain't Over 'til It's Over" singer took to Instagram to pay tribute to the "Aquaman" actor Monday, the day Momoa turned 43 years old.

"Happy birthday, Jason. Love and respect always," Kravitz wrote alongside a photo of himself and Momoa riding motorcycles side-by-side.

"Love [you] forever. Amazing day," Momoa replied, adding four heart emojis.

Fans flocked to Kravitz's post, praising the pair's bond and sending birthday greetings for the "Dune" actor.

"Happy birthday. Two great dads right there," one Instagram user wrote. Another commented, "Possibly one of the coolest photos ever."

"Love this journey for them!" a third person added. "Love the way you love and respect one another @lennykravitz and @prideofgypsies! Happy birthday, Jason! God bless!" a fourth user wrote.

Kravitz was previously married to Bonet from 1987 to 1993, and the now-exes are parents of actress Zoë Kravitz. Despite going their separate ways, Bonet and the rocker have maintained a good relationship. He then developed a close bond with Momoa, who first began seeing his ex-wife in 2004.

Last year, Kravitz opened up about his unexpected bromance during an interview with Entertainment Tonight.

"[Jason’s] a big teddy bear," Kravitz said in October 2021. "He's a kid at heart and that's why I love him. We really love each other. We’re not only family, but friends."

Kravitz also previously shared a photo on Instagram of himself and Momoa bonding with one another over their motorcycles in March, weeks after Bonet and the "Game of Thrones" alum announced their separation.

"Ride or die. Brothers for life," he wrote in the caption.

"Love [you], bro. Ohana for life," Momoa wrote in the comments section.

Zoë also commented on the post, adding, "Well isn't this just adorable. Love you both so much."

Momoa and Bonet announced that they were parting ways after 16 years together via a since-deleted statement posted to his Instagram in January.

In their joint statement, the exes wrote that they'd decided to call it quits after having "felt the squeeze and changes of these transformational times."

"A revolution is unfolding and our family is of no exception… feeling and growing from the seismic shifts occurring," the joint statement read. "And so we share our Family news that we are parting ways in marriage."
