It's two leading ladies in the same sexy leather long-sleved mini!

On Wednesday, "R.I.P.D" star Marisa Miller sported the cut-out Catherine Malandrino dress in cobalt blue to the ESPY awards. The model/actress, who gave birth in December, is definitely not harboring any of that baby weight anymore!

The blonde beauty looked great in the sheer number, wearing her hair straight and parted to the side, and finished her look with nude Christian Louboutin peep-toe pumps.

But she's not the only actress to sport the revealing ensemble!

In April of 2012, Jennifer Lopez wore the memorable look in black onstage at the "American Idol" top 7 live performance.

J.Lo wore her hair straight in half up, half-down 'do and finished her look with black spikey Christian Louboutin heels.

While both of the ladies look absolutely lovely in the Malandrino dress -- we have to give the nod to Marissa! We love the dress in the cobalt color because it accentuates the sheer panels.
