Jennifer Lopez performs Greatest Hits medley on ‘Ellen’...

Revisited memory lane...
Jennifer Lopez gave fans a sneak preview of what to expect from her upcoming Vegas residency. 

She killed the stage with a dance medley of her greatest hits on 'Ellen' earlier today. As far as age goes, J.Lo has 10-15 years on her younger peers. She delivered more dance and energy in a five minute performance than what you see in an entire concert from some of these younger pop chicks. Her residency is going to be one hot slay.
