Being the spokesperson of a skincare brand requires a radiant and clear complexion (a killer smile helps too) and luckily for Biotherm, their latest face has both of those.
Leighton Meester attended a launch event for the brand in Shanghai on Thursday and yep, everyone's favourite Gossip Girl was glowing.
Perhaps that had something to do with those recent engagement rumours?
People magazine reported that Meester and The OC star Adam Brody got engaged this week, but before we get too excited about the ultimate TV couple, have a quick look at Leighton's sparkly ring - it's on the wrong finger!
Leighton used the statement ring as a distraction as she covered up her wedding finger. Clever. Oh, and that striped floral print jumpsuit? The Marchesa Voyage design looked effortlessly chic on the star. We wouldn't expect anything less.
