We wonder how many times Taylor Swift 's hit tune "22" has been played on repeat today...because it's Selena Gomez's birthday! The "Come and Get It" cutie is ringing in the big 2-2 today, and no surprise, she kicked off her special day in a pretty epic way.

Welcome to the show, Kate Hudson, now try to keep a straight face. On Monday's Tonight Show, Jimmy Fallon handed Hudson an assortment of objects, asking her to describe them to him as part of the show's goofy segment called "Box of Lies."

The two were separated by a wall with just a window for their faces; after removing an object from a numbered box, Hudson could choose to describe the box's contents truthfully or not, at which point Fallon had to guess whether she was lying. All things considered, Hudson's efforts were pretty on point.
