NASCAR’s Chase Briscoe and his wife, Marissa, are officially parents of twins.

The couple joint posted to Instagram on Wednesday (Oct. 9), announcing the arrival of daughter Collins and son Cooper.

“Yesterday Marissa and I were able to bring two new blessings into our family,” the professional driver writes, indicating their babies were born on Tuesday (Oct. 8). “Meet Cooper Banks Briscoe & Collins Ivy Briscoe.”

In the photo, the babies are sharing the same hospital bassinet, dressed in blue and pink swaddles. Above their little heads are two acrylic balloons, with “hello world” written on them.

This makes the couple’s older son, Brooks, a big brother. Just a week prior to the twins’ birth, he turned three.

“Happy 3rd birthday to the little guy that has changed my life,” Briscoe wrote on Instagram to honor the occasion. “Being a father has been the coolest and most rewarding thing ever and being Brooks’ dad is the absolute most fun you could ever be.”

The couple first shared the news of their growing family back in April.

“We’ve been keeping a little secret,” their post noted, with the family holding up two onesies to announce the twins. A month later, they revealed that they were having a boy and a girl.

Collins and Cooper are said to be doing well. In a post to Instagram, the new mom of three let followers know her babies are doing great.

“They are here! Mama and babies are healthy,” she writes. “Thank you Jesus!”

These twins aren’t the only fresh babies in the NASCAR world: Bubba Wallace and wife Amanda also recently welcomed baby Becks Hayden into the world recently.
