Gabriella Cilmi has revealed she has a crush on actor Robert Downey Jr., 45. “Robert Downey Jr. He’s a bit old, but that hasn’t stopped a lot of people! I’m only joking,” the 18-year-old Australian singer said, according to Contact Music. “I think he’s really cute and just a total hottie.” But don’t look for the ‘Sweet About Me’ singer to hook up with a soccer player. “They seem to get themselves into quite a bit of trouble,” she opined.
