Saoirse Ronan TIFF 2013: 'The Host' Star Makes Fans Giddy On The Red Carpet (PHOTOS)

If you want to know who your next celebrity crush will be, look no further than the lovely Saoirse Ronan. (That's pronounced "seer-sha" for those not in the know.)

The 19-year-old Irish actress made fans go wild on Tuesday at the TIFF 2013 red carpet premiere of her film "How I Live Now," the likes which we haven't seen since Kristen Stewart or Jennifer Lawrence.

Even Canadian director David Cronenberg's daughter Caitlin, who has photographed celebs such as the one and only Paulina Gretzky, got giddy when she saw the "Atonement" star, tweeting:

"You know who has perfect skin? Nobody. Well, actually just Saoirse Ronan. #TIFF13 #NKPRIT13."

High praise from someone who has seen many a celebrity at the Toronto Film Festival!

But "The Host" actress took all the attention in stride, posing for Instagram photos with fans and signing autographs.

The blond beauty took ethereal to a whole new level in a sheer watercolur stained frock with a cute collar and delicate silk skirt overlay. "The Lovely Bones" actress accentuated the look with dark red lips and avant-garde black-and-grey pumps which gave the ensemble some edge. Quite a change from the innocent budding starlet we saw back at TIFF 2011!
