Has Katy Perry been naughty or nice?
She let beau John Mayer decide on Christmas day, tweeting a photo, where she called him her “Santa Baby.”
The two singers have been dating on and off since August, but things seem pretty serious considering they're already spending holidays together!
The 28-year-old has been spending lots of time with the bad boy, going on concerts and dinner dates, since divorcing Russell Brand in Dec. 2011 after one year of marriage.
Do you think Katy and John are good together? Let us know in the comments!
