Dancing With the Stars champ Helio Castroneves is going to be a father!

The three-time Indianapolis 500 champion, 34, confirmed that he and girlfriend Adriana Henao are expecting a baby girl in January. They've already decided to name her Mikaella.

"We thought about calling her Indy, but we thought that might be a little too much," Castroneves -- who won his third 500 race in May -- told IndyStar.com at Homestead-Miami Speedway Tuesday.

Although the Brazilian race-car driver -- who won DWTS with partner Julianne Hough in 2007 -- 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.
