Blake Lively red carpet gown dress blue chiffon train cleavage red hair ring teal

Blake Lively has gone from blonde to red, and the Gossip Girl star certainly pulls it off!

While hitting the red carpet at the Time 100 Gala in New York, Ms. Lively showed off her new mane and a whole lotta cleavage in a sea foam green Zuhair Murad Couture gown. Simply divine!

The 23-year-old actress dyed her blonde locks for her upcoming role in Hick. If she was going for a live-action film based on The Little Mermaid, we'd definitely go under the sea with her!
