Diane Keaton is cheekily celebrating her birthday with a sprinkle of her signature comedy.

The Something's Gotta Give actress posted a montage of birthday cakes, all different types, sizes, and flavors, along with a humorous self-affirmation.

"HAPPY BIRTHDAY TO THE LOVE OF MY LIFE… ME!" the legendary actress wrote alongside her birthday cake slideshow.

Several of the actress's famous friends chimed in and wished the star a happy birthday, too.

Kris Jenner shared well wishes to her friend, writing, "Happy Birthday beautiful!!!! Sending you lots of love ❤️🙏😍🥰."

Keaton is sure to keep people laughing in her upcoming movie, Maybe I Do. Last month, Vertical Entertainment released the trailer for its upcoming romantic comedy starring Keaton and Richard Gere, plus Susan Sarandon and William H. Macy as married couples involved in affairs with each other — until they realize their children, played by Emma Roberts and (her Holidate costar) Luke Bracey, are considering getting married.

Maybe I Do's trailer teases the relationship chaos that gets underway after Allen (Bracey) deliberately prevents Michelle (Roberts) from catching a bouquet at a friend's wedding, signaling to her that he may not be ready to take a step toward engagement.

Maybe I Do is in theaters on Jan. 27.
