"I'm such a die-hard fan," the Dancing with the Stars contestant, who recently earned a perfect score, told PEOPLE. "I get violent when I watch Celtics games."
The Boston-area native's love of her hometown sports teams is well-documented, having recently donned a bikini in New York Giants colors after losing a Super Bowl bet on her beloved New England Patriots.
"We were watching [game 3 of the NBA playoffs] at the reception desk of the Dancing rehearsal house and there was a kid sitting in front of me on the computer – and I was squeezing, assaulting his shoulders every time the Celtics would do something amazing," she said.
The Dancing with the Stars contestant look a break from her sports-watching and rehearsing on Saturday to celebrate the launch of Bud Light Lime-a-Rita poolside at Las Vegas's Mandalay Bay. But, considering the Celtics are still in the play offs, she says no one is safe when a game is on.
"Derek [Hough] is a little scared," she said. "I get a little crazy."
