She and 1969 Indy 500 winner Mario rolled onto the track with the field of 33 drivers before Sunday's race in a custom-built, two-seat Indy car.

Gaga was a late substitute for country star Keith Urban, who was unable to participate after injuring his back.

The singer gave the racing icon and team owner Michael Andretti kisses on the cheek before the start of the race.

"Travel to any corner of the globe and people know exactly who Lady Gaga is," Indianapolis Motor Speedway president Doug Boles said.
