Leighton Meester: Real Madrid!

Leighton Meester is looking gorgeous as she launches the new line of hair cosmetics from Herbal Essences on Wednesday (May 5) in Madrid, Spain.

It was announced last month that the 24-year-old Gossip Girl actress was named the Herbal Essences Global Ambassador.

Leighton and her co-star Sebastian Stan are still dating, JustJared.com exclusively reportedly earlier this week. The couple was spotted making out in a car prior to one of the MET Ball after-parties in New York City.

FYI: Leighton is wearing an Herve Leger dress and Pierre Hardy sandals.
