Still trying to decide what to do on New Year's Eve? How about dropping up to $25,000 on a table, poolside bed or cabana at the Haus of GaGa.

Lady GaGa will be performing at the Fontainebleau Hotel in Miami on Dec. 31. The swanky spot's website is listing tickets from $425 to the aforementioned five-digit sum, with special DJ guests David Berrie and Jus Ske.

The artist will also be taking the stage at another locale in Miami earlier in the evening, at the James L. Knight Center, as part of her ongoing Monster Ball Tour.

If you're in New York, there are tickets still on sale for Mariah Carey and hubbie Nick Cannon at Madison Square Garden. If you're in L.A., Adam Lambert is still taking buyers for his Gridlock event, with MC Pamela Anderson, at the Paramount Pictures Studios.
