Looks like Christina Aguilera is planning to ring in the new year with a killer party!

Party rental trucks have been dropping various items off at Xtina's house ... including what appears to be pieces of a dance floor.


We contacted Classic Party Rentals in El Segundo to ask about Xtina's NYE party, and they tell us it costs more than $1900 to rent a dance floor. That's pocket change for the sexy Burlesque diva!

Now that Christina has a new beau, looks like the hot mama will be kicking up those Christian Louboutins in style!
