Kristin Cavallari is reportedly annoyed that the sex of her baby has been revealed.
Cavallari and her fiancé Jay Cutler announced in January that they are expecting their first child.
However, Cutler's Chicago Bears team mate Earl Bennett recently revealed during a radio interview that the couple are going to have a son.
Cavallari and Cutler are now said to be annoyed that the sex of their baby was revealed, Hollyscoop claims.
"They are not happy that something so personal was revealed on a radio show, especially Jay," a source alleged. "He didn't want anyone to know what they were having."
Cavallari previously revealed that she did not plan to get pregnant but considers it "fate".
