Dominican-American singer Kat Deluna started her day at ‘Good Day NY’ this morning performing her latest single ‘Drop It Low’.  The ‘Whine Up’ singer got a little ‘back-up’ from a surprise guest at the performance’s end.

Needless to say, Deluna dropped something. We’ll let you decide what. See Snooki the songstress after the jump:
