E Online has an exclusive that no self-respecting golf writer would have dared (or thought of) to ask about.
"Justin Bieber is the only person I talked to on the phone that night after I won," Watson revealed. "He called me and I talked to him on the phone and he and Selena were congratulating me, and it was a big honor that they would both call me and talk to me."
The video can be viewed here. I'd embed it, but it automatically plays and I find that annoying.
