Bradley Cooper's leading lady is finally opening up about dating one of the sexiest men in Hollywood.
The 21-year-old model added, "I'm not one of those girls who goes on about their boyfriends. I do think whatever I say will sound weird. But the truth is, if it start talking about him, I probably won't be able to stop. And I don't really want to talk about him, you know?"
The gorgeous blonde was most recently spotted in Hawaii visiting her beau, who is currently filming a movie in Honolulu.
The two were spotted playing at the beach and engaging in some serious PDA in the water.
Cooper and Waterhouse were first romantically linked in March and have been cozying up around the globe ever since.
Despite their 18-year age difference, things seem to be going well for the budding couple.
In fact, Waterhouse is finally getting used to all of the criticism that comes with being in the public eye (and being linked to Cooper).
"I try not to look at that stuff. In reality, if there are 200 people commenting on something online, it's less than a grain of salt in a huge beach of humanity—who cares? I just want to work hard, do stuff of the best possible quality and be a great friend." (And of course, great girlfriend.)
