Justin Timberlake & Ellen DeGeneres - VIDEO

Funny stuff, Justin Timberlake shocked Ellen yesterday by calling her up during her show to wish her a happy 50th birthday...

I think it was the Mary Poppins impersonation that threw her, LOL.

"I called to say happy 70th (and) to tell you you look so freakin' hot. And remember, Ellen, 50 is the new 60."

Ellen celebrates her 50th birthday this Saturday..
