Well who did you expect her to bring? Russell Brand??
Katy Perry certainly deserved to have an AH-Mazing night out after she rocked the Saturday Night Live stage with two killer performances.
And we're guessing she had just that kind of night as John Mayer stepped out with the candy-coated cutie for the SNL after party.
The two might have looked totally low-key while they made their way to the festivities, but those smiles on their faces are awfully telling!
We just know they celebrated all night long and hopefully all morning long back in bed. Wink wink!
