Leighton Meester and New Man Get Romantic in Rio (PHOTOS)

Leighton Meester was spotted wrapping up her birthday week in Brazil with a man identified as (virtually-unknown actor) Aaron Himelstein. They could’ve been two friends just enjoying the sites but their close proximity to each other in these photos (and others) suggest there’s a little more than just friendship there. Leighton has previously been (loosely) linked to her Going the Distance co-star Justin Long and Entourage guest-star Joshua LeBar, but this out-of-country rendezvous seems to look a bit more serious than a simple dinner date in Hollywood.
