lady gaga grammys 'Saturday Night Live': Lady Gaga joining Justin Timberlake for finale?On Tuesday, word leaked that Justin Timberlake will host this season’s “Saturday Night Live” finale when an unwitting staffer accidentally posted the news to “SNL’s” Twitter account. Oops.

Now, the New York Post is reporting that Timberlake will be joined by musical guest Lady Gaga, whose new “Born This Way” CD drops two days after the May 21 season ender.

Gaga last took the “SNL” stage in 2009 — not only as musical guest, but teaming up with Madonna for the “Deep House Dish” sketch (watch it below). Timberlake, of course, has taken on regular status — if he does indeed take the stage on May 21, it will be his fourth time hosting.

All we need now is Alec Baldwin, and we’ll have a trifecta of perfection.
