Lenny Kravitz and Jason Momoa's longtime bromance is still going strong! The musician wished his fellow superstar a happy 43rd birthday on Aug. 1, posting an Instagram photo of the pair riding motorcycles together. "Happy Birthday, Jason. Love and respect always," he wrote in his caption. Lenny and Jason grew close while the "Aquaman" star was married to Lenny's ex-wife, Lisa Bonet, and they clearly continue to think of themselves as a blended family.
