Jennifer Lopez AMAs 2014: Singer's Blush Dress Is Her Hottest Yet

There was a lot of competition on the 2014 AMAs red carpet but Sunday night easily belonged to Jennifer Lopez.

Proof: the 45-year-old stunner flaunted her ab-tastic bod in a blush Reem Acra dress that left little to the imagination.

Once again JLo proved that she had the best figure in the biz in the sexy frock that showed off her toned torso and her killer legs. Her hair and makeup were on-point too: slicked back tresses, a nude lip and a smoky eye highlighted her gorgeous face.

The "American Idol" judge also killed it on stage when she and Iggy Azalea performed their hit song "Booty."

For the performance, the "True Love" author changed into a sparkly red bodysuit that naturally showed off her famous derriere.

Looking good, girl!
