One is a sexy Hollywood starlet.
The other is an aging actor who, according to the Internet, once sold his soul to the devil in exchange for unparalleled martial arts skills, then - in an ironic twist - roundhouse kicked the devil in the face and took his soul back.
So what do Scarlett Johansson and Chuck Norris have in common?
They both backed winners in Thursday's Iowa caucuses. Yes, with a little help from their celebrity fans, Democrat Barack Obama and Republican Mike Huckabee emerged victorious in Iowa's first-in-the-nation vote.
While Chuck Norris, 67, stumped for Mike Huckabee in December and was with him last night, Johansson, 23, was by Obama's side, speaking at a rally for high school and college-aged "Barack Stars" in Coralville, Iowa, this week.
Scarlett Johansson urged younger Democrats in Iowa to help deliver a Barack Obama victory, and they obliged as the Illinois senator won the caucus.
"She actually seemed a little shy when she started speaking," audience member Jason Millsap said. "But she warmed up to the crowd ... It was pretty exciting and inspiring to see someone as big as her come and talk to her peers."
"[Scarlett Johansson] was asked a question as to why she chose to support Barack Obama and answered it very well, in my opinion," added high schooler and caucus goer Peter Caroll. "She [explained] how she did research him and found Obama to be [passionate about] most of the issues she deemed important."
Young voters, like Johansson and her fellow Barack Stars, may have been a key to Barack Obama's victory over John Edwards and Hillary Clinton. Obama took an estimated 57 percent of the under-30 vote, according to CNN.
