One Last Time (Jason Reilly Remix) Ariana Grande
Lady Gaga's been challenged to a live singing contest, where the winner walks away with at least $1 million.
The challenge has come from an LA recording artist called Alisa Apps who wants to take on the megastar at either New York's Madison Square Garden or London's O2 Arena.
"I feel sorry for Lady Gaga -- she's just a plastic doll generated by the music money marketing machine," says Apps. "This contest gives people a chance to choose which they prefer -- plastic or real."
Lady Gaga has yet to respond to the challenge. The contest would see each singer performing a series of songs in front of a live audience.
So who is Alisa Apps. Well, she's yet to release her debut album, but a clip of her track "How Do I Make Right" has so far attracted over 1.2 million views on YouTube. Take a look for yourself here.
