Quick offensive question?

When you break away from the defenders, what buttons do you hold to celebrate when your running into the endzone?

I think that holding down circle does it, or B on the 360.

B spins, I"m thinking you hold down RB, RT, or LB along with B, but I havent got the game to try it, its on its way here now.

I know B spins, but when your breaking away inside the 20 yard line, if you have like an 8 yard cushion or something, you can taunt as your takin it to the house.
