Blue Belle: Emmy Rossum Does Summer Chic In Winter (Well, She Is In LA)

Beautiful Creatures actress Emmy Rossum was blooming in blue for her Tonight Show appearance this week, but you'd be forgiven for feeling the chill just looking at her Summery frock *brrrr*. Well, let's not forget she's in LA and it's probably a few degrees warmer there...

The 26-year-old looked drop-dead gorge as she slipped into a lacy cobalt Catherine Deane tea dress and took to the stage for a chit chat with host Jay Leno. Teeing off the look with a poppy red lip and loose waves, Emmy was certainly a belle in blue.

Before making her way to the recording studio Emmy admitted she was feeling a little worn out after jetting back to the US after promoting her new flick in Russia. She tweeted:

If that's what jet lag does to a girl then we need to fly long-haul more often.
