Michael Andretti has been in the news the past few weeks primarily concerning matters that his team may expand to five cars next season.

His other team, the personal one at home is expanding too as Andretti announced through his Twitter on Monday that he and his wife, Jodi Ann Paterson, are expecting twins -- their first children together.

Andretti has three other children: Marco, 26; Marissa, 22; and Lucca, 14.

Andretti Autosport's future is less certain.

Defending IndyCar Series champion Ryan Hunter-Reay is under contract for next season and Marco and EJ Viso are expected to finalize deals the coming months. The team is also working to retain the services of three-race winner James Hinchcliffe and could also pick up defending Indianapolis 500 runner-up Carlos Munoz, who competes for the team in the Firestone Indy Lights Series.
