How to impersonate Jennifer Lopez?

My school is having an American Idol spoofed talent show, & I was chosen to be one of the judges after each performance. Of course it's just for show, the real judges will be in secrecy. But I had to come up with a name for her and I chose J-HI instead of J-LO. Now I need some advice of funny things to say after each performance and what to wear. Any input or help will be appreciated! I really want to make this funny and memorable :)
