Jennifer and Heidi at the Back-Up Plan Premiere

Jennifer Lopez on the red carpet for the Hollywood premiere of her new movie, The Back-up Plan.

Jennifer flattered her figure in a form-fitting silver dress from Gianfranco Ferre, accessorized with Ferragamo pumps, Louboutin clutch and Cartier jewels.

Joining J Lo at the premiere was mom-of-four Heidi Klum who shimmered in a glittering dress from Project Runway designer Emilio Sosa.

She paired the strapless dress with lilac and black Christian Louboutin sandals.

Heidi's Christian Louboutin "Zigounette" Sandals are on-line at net-a-porter.com.
