Jessica Simpson mistakenly told her boyfriend Tony Romo’s family she was pregnant.

The singer is reportedly desperate to have a baby with her American football player beau and was delighted when a home pregnancy test revealed she was expecting a child.

The couple were so excited by the news they immediately decided to tell Tony’s family, and were shocked by their furious reaction.

A source said: “There was a huge fight on July 18 at the Romo home. Jessica and Tony thought she was pregnant and happily announced it to the family.

“The news resulted in dead silence. Then Tony’s dad Ramiro said, ‘You’re not married. This is crazy!’ Tony’s mom Joan joined in, demanding, ‘How can you do this to us?’”

Jessica, 28, is said to have been devastated at the family’s response, especially as she was later forced to admit she had made a mistake after allegedly misreading the test.

The singer’s younger sister Ashlee, 23, announced she is expecting a child with her husband Pete Wentz earlier this year, and the news has made Jessica want a child even more.

A source added to the National Enquirer magazine: “Her friends know she’s feverishly trying to conceive.”
