Scarlett Johansson Sizzles at "The Avengers" UK Premiere
"The Avengers" world tour continues ... the super-talented -- and super-hot -- cast hit the red carpet in the United Kingdom on Thursday night!
After premieres in the US and Russia, Scarlett Johansson, new dad Robert Downey Jr., dad-to-be Chris Hemsworth and more debuted the super-hero flick in London, surrounded by throngs of screaming fans. 
The stars looked patriotic in red, blue and ever-present black, with Scarlett and Cobie Smulders stealing the show in Prada and Alexandra Vidal, respectively.
Chris' very pregnant wife, gorgeous Spanish actress Elsa Pataky, donned a green gown as well as the apparent hair trend of the evening -- a French braid, just like Scarlett!
