It's been a decade since the world first got a look at Suri, bundled up in Cruise's coat, on the cover of Vanity Fair in October 2006. "She has Kate's lips and eyes," Tom said in the pages of the magazine. "I think she looks like Kate." Katie chimed in, "I think she has Tom's eyes. I think she looks like Tom."
