And Ryan Reynolds and Sandra Bullock teamed up to honor the comedy legend by singing her a sweet and hilarious rendition of "Happy Birthday" during an Instagram post.
The Hollywood heavyweights -- who starred alongside White in the 2009 romantic comedy "The Proposal" -- took turns singing the verses before Sandra threw in, "From Sandy, who loves you more than Ryan," while Ryan responded, "From Ryan, who loves you SOOO much more than Sandy."
Then Ryan went off on a funny tangent while Sandy kept singing the tune.
"What does Sandy do for you every year, does she like -- show up and hand deliver flowers to you -- and wearing nothing but black socks and a -- a dozen gold bracelets -- just like you requested? I doubt it."
Sandy finished with an air kiss and a birthday wish, while Ryan hammed it up pretending to cry.
Watch the amazing tribute below.

The post -- which had almost 2 million views in an hour -- was a great tribute to the acting icon, who holds the Guinness world record for longest TV career for a female entertainer, having first started with a variety show called "Hollywood in Television" in 1949.
Her most memorable turns came when she portrayed Sue Ann Nivens on "The Mary Tyler Moore Show" and Rose Nylund in "Golden Girls." She found luck again with the sitcom "Hot in Cleveland."
She also holds the title as oldest celebrity to host Saturday Night Live, which she did to perfection back in 2010, winning her an Outstanding Guest Actress in a Comedy Series Emmy, bringing her total Emmy wins to eight.
