Britney Spears debuted her new single “3” and take a wild guess what it’s about.

“Three is a charm
Two is not the same
I don’t see the harm
So are you game?”

Spears loves controversy, and she’s courting a fresh batch with the new song off her upcoming best-of-compilation “The Singles Collection” from Max Martin, the Swedish producer who created Katy Perry’s “I Kissed a Girl” and Spears’ “If U Seek Amy.”

“Merrier the more
Triple fun that way.”
