Did you catch Jennifer Lopez performing her single, 'First Love' from her forthcoming album "A.K.A" on the American Idol Finale last month? Her performance was awesome! She killed it in her sexy blue sequence dress, along with her voice and dance moves.

J Lo is schedule to perform at this year's Chicago's B96 Pepsi SummerBash on Saturday, June 14th @ Toyota Park.

And guess what??..... She's still Jenny from the Block!

Let's rewind and watch her performance below!
