Lady Gaga + Justin Timberlake Give Us Sneak Peak into ‘SNL’ Finale

Who's excited for the weekend? We are, but that's because this one will be extra special, as Justin Timberlake is hosting the 'SNL' Season finale -- and Lady Gaga is the musical guest! Thanks to Mama Monster and her tweeting ways, we were able to get a brief glimpse behind-the-scenes before it airs.

"Don't be jealous ladies. I laughed so hard today I cried. #TimberGagaSNLFinale," Gaga tweeted last night, including the photo of her and J.T. you see above. The pair will join forces tomorrow night, May 21, on the 'Saturday Night Live' Season finale.

We had no idea Timberlake was such a comedian until he got involved with the Lonely Island a few years ago. Now, he's getting gigs like this one all over the place -- and we couldn't be more proud of how far our little 'N syncer has come! This week, he and Andy Samberg also goofed off in preparation for the 'SNL' curtain close.

As for Gaga, even though this isn't her first 'SNL' musical spot, this one is going to be epic, as it's just one more way to amp up the world for 'Born This Way,' which (finally) drops next week. Come on, Saturday!
