Tyson Fury Announces Wife Pregnant With 7th Child

Tyson Fury is in a MUCH better mood after going TF off on Oleksandr Usyk earlier Thursday ... 'cause the boxing superstar announced his wife is pregnant with their 7th baby!!

Just hours ago, the Gypsy King publicly unleashed on Usyk after the two sides couldn't agree on terms to throw hands in the ring next month ... cussing up a storm and claiming his potential opponent was scared.

But Tyson transformed into a completely different man a short time after ... smiling from ear to ear as he shared the big news on Instagram.

"All is not lost!" Tyson said. "I get to do Date night with my beautiful pregnant wife [Paris]. 7th [baby] incoming."

"fantastic news to cheer me up."

Of course, Fury has previously made his intentions to expand their family very clear ... saying he was ready to put a "bun in her oven" last year.

The Furys have kids ranging from one to 13 years ... and even with lucky #7 on the way, there's no telling when they'll be done growing their family!!
