Dancing With the Stars champ Helio Castroneves is a father!

The three-time Indianapolis 500 champion, 34, confirmed on Twitter that he and girlfriend Adriana Henao welcomed a baby girl named Mikaella on Monday.

The star also posted a photo of his newborn -- who weighs 7 pounds, 3 ounces, and is 19 inches tall.

When he announced the pregnancy in October, Castroneves joked that they thought about "calling her Indy."

Although the Brazilian race-car driver -- who won DWTS with partner in 2007 and won his third 500 race in May -- and Henao have not made plans to wed, he said marriage is "the natural next step."

Most recently, Castroneves made headlines after he was indicted for federal tax evasion and fraud after allegedly failing to pay more than $5 million to the IRS over a four-year period. He was cleared of those charges in April.

"This year started very difficult, the middle was kind of a 'Wow!' and now this," he said in October. "This is a great ending for the book."
