Watson was briefly linked to the "Made in Chelsea" star and diamond heir in 2008 after they were spotted flirting at a Cartier polo party that summer. In an interview with Heat Magazine in 2011, per The Sun, Boulle opened up about their fling and said, "We had a bit of a thing a while back."
Boulle also explained why he decided to break things off with the actor. "I have always been an ambitious person, and I want to achieve my own notoriety for what I've done. That's why I chose not to pursue it any longer, because I didn't want to be the boyfriend of some child actress," he said. "I actually really like Emma. She's a really cool person. She's a very different person to who she is in the media. That's what I liked about her — she's very interesting."
