's father is used to seeing his daughter dance sometimes seductively with men, but when he saw her recent pictorial in Sport Illustrated's Swimsuit Edition
, he waltzed right out of the room.
"I just talked to my mom today and she was like, 'Me and your dad just saw you on TV in your bikini,'" she told PEOPLE Wednesday at a launch party for the issue at the Mirage Hotel in Las Vegas. "My dad had to walk out of the family room because he felt really uncomfortable."
The photos, taken with Burke's former Dancing With The Stars
partner Maurice Green
, took the pro, 25, a bit out of her comfort zone, she said, because the outfit was smaller than what she usually wears.
"I was in a teeny bikini which I'm not used to," she said. "I'm used to dancing around in little things."
Those "things," she said, her father can handle. The bikini "was too tiny for him, but it was covered in diamonds, so that has to count for something. Sorry dad!" Check out more photos of DWTS pros with sports stars. --Mark Gray
