Los Angeles: Actor Will Smith refused to let his "Suicide Squard" co-star Margot Robbie tattoo him. Robbie showed up on the set of "Suicide Squad" with a tattoo gun and offered to ink her co-stars, including Smith and Cara Delevingne, but he was not impressed. "I'm a grown-a** man. Margot comes bounding into work with all of her 24-year-old glory like, 'Guys! Guys! I got a tattoo gun! I got a tattoo gun! We're all getting tattoos!' I was like, 'No, we're not'," Smith told etonline.com. Robbie said her tattoo skills leave a lot to be desired. "Picture what a four-year-old would draw and stick it on your fridge. That's kind of one of my tattoos," she said.
