It's official: the veteran comic has sold a book to New York publishers with his own special take on getting older.

Billy Crystal has sold a humor book about aging for $4 million, a source tells The Hollywood Reporter.

The 64-year-old actor-comedian-Oscar host has inked a deal to write a book to be released in conjunction with his 65th birthday in March, Stephen Rubin, president and publisher of Henry Holt and Co., said Thursday.

As THR previously reported, Crystal already has penned the tome on senior citizenship, which sources say is "hilarious."

CAA, which reps Crystal, brokered the deal.
