Derek Hough is happy to keep spreading the word about healthy habits.
"This guy right here, he is a paparazzi, but I've been teasing him and telling him, 'You better get in here man,' and look at where he is," Hough proudly says. "He came. He came!"
The paparazzo then reveals he's already lost 20 pounds in a month.
"Twenty pounds in a month ... this guy right here," Hough says. "Give me a high-five brother."
"I think that we just have great chemistry," Hough said about Lopez. "We hit it off really well. We have a good banter between each other. She's cool. I mean, she's not just another person because she's J. Lo, but what you definitely feel comfortable around her for sure."
