Indy racer Helio Castroneves and his partner Adriana Henao welcomed a baby daughter on Monday in Atlanta.  They named their first child Mikaella Castroneves and the proud dad wasted little time in posting the first family 'twitpic' on his Twitter page.

The baby arrived more than a week earlier than the couple had anticipated.  Henao's due date had been calculated as January 6, 2010.  Their daughter weighed in at 7 pounds 3 ounces and measured 19 inches long.
