The 67-year-old actor feels that Robin, 37, who announced his separation from actress wife Paula Patton, 38, in February will convey his heartbreak through music, reported Us magazine.
"From my perspective, I always let Robin speak through his music. He's in the middle of a great album right now. A lot of power in the album," he said.
Alan, who is married to former model Tanya Callau, said that he is fine with whatever Robin and Paula decide.
"We love them, they're great people. Whatever they decide to do, it will be the right thing," he added.
