The NASCAR star's first son Leo Benjamin was born on Monday, reports People.
"He's happy and healthy, and mum is doing great," Gordon posted on his official website.
New son Leo joins 3-year-old sister Sofia.
Gordon announced Vandebosch's pregnancy in February.
"We're very excited and can't wait to expand our family to four. Ella is also very excited and can't stop talking about how much she's looking forward to being a big sister," he said earlier this year.
