Singer Jennifer Hudson's fiance, David Otunga, said he is "impressed" with his future wife's weight loss.

"I'm as impressed as everybody else," the 31-year-old wrestler told Us Weekly on Thursday.

Hudson, 29, shed about 80 pounds in the past year --going from a size 16 to reportedly a size 0 through a Weight Watchers program.

"She's always been super confident," Otunga said. "She hasn't really changed, to me."

The couple, who got engaged around 2008, have a 2-year-old son, David Jr.

"We had a huge party." Otunga said. "We rented out this park. He had a wrestling ring we made for him and we rented out a jumping castle. All of his friends came."
