Diane Keaton Celebrates 77th Birthday With A Funny Post [Photos]

Diane Keaton welcomed her 77^th year with humor.

"HAPPY BIRTHDAY TO THE LOVE OF MY LIFE... ME!" the actress wrote on her Instagram page Thursday alongside a slideshow of opulent birthday cakes in different types, sizes and flavors. A woman, presumably Keaton herself, is heard singing "Happy Birthday to me" in the background.

Fans and friends of the veteran actress sent their well-wishes on her Instagram page.

Comedian Sarah Kate Silverman commented, "LOVE!! Happy birthday, brightest of lights!" Kris Jenner also greeted Keaton and wrote, "Happy Birthday beautiful!!!! Sending you lots of love."

"Happy birthday icon," "Pretty Little Liars" alum Lucy Hale commented while Mary Steenburgen added, "Happy birthday, you funny bunny!😍I love you so much!!!"

One fan wrote, "Happy Birthday! Getting older is so....interesting, isn't it? You do it well! (75 year old here...)"

"I'm sooooo glad you were born! My 100% style inspo forever and always)" another fan commented.

Amy Sedaris, Kristin Chenoweth, Mario Lopez and New York Times bestselling author Danny Pellegrino also joined in with their birthday greetings for the actress.

On the work front, Keaton is starring in the upcoming romantic comedy film, "Maybe I Do" alongside fellow veteran stars William H. Macy, Richard Gere and Susan Sarandon, as well as Emma Roberts and Luke Bracey. The movie follows the story of two married couples who are involved in affairs with each other. Things turn chaotic when the parents find out that their children, played by Roberts and Bracey, are considering getting married.

Last month, Vertical Entertainment released the trailer for "Maybe I Do" which opens with a scene showing Allen (Bracey) preventing his girlfriend Michelle (Roberts) from catching the bouquet at a wedding. "It was a reflex action," he later explains to a furious Michelle. She replied, "It was the most awful moment in the whole history of women being stuck with you idiots."

The pair eventually patch things up and make their parents meet over dinner to discuss their plans for marriage. Chaos ensues after each of the four parents realizes the complicated situation they are in.

The movie is written and directed by "Boy Meets World" writer and producer Michael Jacobs. "Maybe I Do" is set to hit theaters on Jan. 27.
