“He’s having a boy,” Bennett, 25, said on the Boers & Bernstein sports radio show in Chicago on Tuesday. “I am excited for Jay. It’s a great time.”

Kristin, 25, announced her pregnancy in January, revealing she and her quarterback fiance were having their first child this summer.

“I think every guy wants a guy to carry on the name,” Cavallari told Glamoholic in March. “But he doesn’t care. I just want to have a healthy baby.”

Kristin Cavallari is putting her wedding plans off until after her baby is born.

The former reality star, who is expecting her first child with her fiance Jay Cutler, said she will not be walking down the aisle with a baby bump.

Kristin revealed, “I’m not even looking for a wedding dress right now. I’m pregnant! I’m not going to go try on wedding dresses.”

The 25-year-old, who is known for her stint on the MTV reality show “The Hills”, said her little one will never appear on screen.
