T.J. Watt has found the new center of his whole world. 

The Pittsburgh Steelers linebacker and his wife Dani Watt announced they welcomed their baby girl, Blakely. 

“Worth the Wait,” Dani and T.J., who wed in 2022, wrote in a joint Instagram post March 10, alongside several adorable black and white photos of their daughter’s first days. “Welcome To The World Blakely Marie Watt!”

And naturally, T.J. and Dani’s loved ones couldn’t help but gush over their brand-new bundle of joy. T.J.’s brother J.J. Watt, who played 12 seasons in the NFL as a defensive end, wrote in the comments, “Welcome to the world Blakely!!!!!”

Meanwhile, Marissa Lawrence, who just welcomed her and Jacksonville Jaguars’ Trevor Lawrence’s first baby girl in January, effused, “She is perfect!!! Congratulations, being a girl mom is the BEST!!”

In photos from T.J. and Dani’s exciting life update, their baby girl lays in front of a sign that aptly announces, “It’s a girl!” Another shows T.J. walking down a hospital hallway with Blakely sleeping soundly in her car seat, wearing a beanie with a bow attached to it.
