The win secured the Chiefs’ 6-0 record, making them the only undefeated team in the NFL after the Minnesota Vikings’ loss to the Detroit Lions.

The Mahomes’ were high school sweethearts, growing up in Whitehouse, Texas, with the couple tying the knot in March 2022.

They welcomed their first child daughter Sterling, 3, in February 2021, with Bronze following in November 2022.

The couple announced they were expecting their third child back in mid-July with a video of their two kids holding their ultrasound images.

‘Round three, here we come,’ the couple captioned the Instagram post, revealing just a few weeks later they were expecting another girl.

Shortly after revealing their third child was on the way, Patrick joked that he was ‘done’ having kids after their third arrives.

‘I’m done. I’ll say that. I said three and I’m done,’ Mahomes joked about his children back in July.

He added, ‘“I always wanted to have kids young. I got to grow up in the locker room, I think I’ve talked about it before — it made such an impact in my life, so I wanted to have kids young.’

Mahomes is the son of former Major League Baseball pitcher Pat Mahomes, who pitched from 1992 to 2003.

The quarterback added that Brittany, ‘does a great job’ as both a wife and mother, saying, ‘We still go out and enjoy our life and let our kids see these great things.’

‘It is really cool ‘cause I spend so much time in the building at football for these eight, seven months, and whenever I’m with my family, I wanna enjoy those moments,’ he said.
