Hubbard, 32, and Hayley married back in July 2015 following a nine-month engagement — and the second-time mom-to-be’s first pregnancy was anything but boring.

The “This Is How We Roll” singer and his wife revealed that they were having a boy in June 2017 during a Dirt Bikes or Diamonds party, but were thrown a curve ball when they found out they were actually expecting a daughter.

“Gods got jokes … After thinking we are having a boy for the last few months, turns out the blood test was wrong and we’re actually having a little girl,” Hubbard explained on Instagram in August of that year. ” … So many emotions but really excited about this next chapter … ”

The Grammy-nominated artist opened up to PEOPLE following Olivia’s birth about how much he admired his wife’s demeanor during labor and delivery.

“I think it’s something that God doesn’t let men do for a reason — I don’t know if we could get through it,” Hubbard admitted of childbirth with a laugh, adding that he “100 percent” had a new respect for both Hayley “and all women who have babies.”

Continued the new dad, “It’s a beautiful thing, and Hayley was really strong and calm and relaxed. I couldn’t have been more proud of her the whole time.”
