Ryan Reynolds looked dapper in a skinny tie and slacks as he arrived for his appearance on The Late Show With David Letterman this evening in NYC. The actor is back from a recent trip overseas, where he started his latest round of promotional duties for Green Lantern with a visit to BBC Radio's London studios. After his TV appearance tonight, he'll be hopping on a plane yet again, heading to LA for tomorrow's big premiere of the movie with his leading lady Blake Lively. The duo took the stage together at the recent MTV Movie Awards, and are now both making the interview rounds as they drum up publicity for their superhero film. Blake was on Live! With Regis and Kelly this morning, and talked a little about her recent trip to France, where she was spent lots of time cozying up to Leonardo DiCaprio. She kept mum on her new man, instead chatting about her love of the country's cuisine and culture.
