Justin Timberlake was guest host of the glorious Saturday Night Live season finale with musical guest Lady GaGa on Saturday (May 21)- watch videos below. The singer turned actor did a pretty good job – he had the opportunity to sing a little song about not singing, play with Lady GaGa and reunite with Andy Samberg for a digital short sketch.

Justin, who performed the double-duty as host and musical guest in the past, promised to not sing, which eventually happened during his opening monologue. Then he went against the GaGa in a celebrity edition of “What’s That Name?” to win money for their charities of choice. GaGa won, of course!

The dynamic duo, Justin and GaGa, was the big highlight of the show, which reached the climax in a “threesome” with Andy Samberg in the digital short “3-Way”. This was probably one of the most memorable SNL season finales ever.
