Vroom vroom!

NASCAR superstar Jeff Gordon and his wife Ingrid Vandebosch will welcome their second child this August. Gordon, 38, announced the "exciting news" to fans on his website Thursday.

"Ingrid is 12 weeks pregnant and expecting our second child," the racer wrote.

"We're very excited and can't wait to expand our family to four."

40 year-old Vandebosch, a model and actress, gave birth to their first daughter, Ella Sofia, in June 2007. The couple married in November 2006.

"Ella is also very excited and can't stop talking about how much she's looking forward to being a big sister," Gordon added.
