Leighton Meester: Rio with Aaron Himelstein!

Leighton Meester wraps her arm around her former boyfriend Aaron Himelstein on Friday (April 13) in Rio de Janeiro, Brazil.

The 26-year-old Gossip Girl actress visited the famous Christ the Redeemer at the top of the Corcovado mountain in the Tijuca Forest National Park. Leighton joined the crowd of tourists and took pictures of the iconic statue.

Later in the day, Leighton made time to take pictures and sign autographs for her fans at her hotel.

FYI: Leighton and Aaron used to date back when they made the film Remember the Daze in 2007!
