Indy car driver and former Dancing With the Stars champ Hélio Castroneves and girlfriend Adriana Henao are first time parents!

The couple welcomed daughter Mikaella at 4:15 p.m. Monday, December 28th in Atlanta, and apparently dad isn’t the only one with a need for speed. Baby girl — who weighed in at 7 lbs., 3 oz. and measured 19 inches in length — arrived slightly ahead of schedule, more than one week before her January 6th due date.

Hélio, 34, Tweeted the happy news, even sharing a picture of his new family of three.

The pregnancy was announced in October.
