Charlize Theron cheering for Danica in NASCAR finale

Charlize Theron is cheering for Danica Patrick in her final NASCAR race.

Theron is the honorary starter for the Daytona 500 and will wave the green flag to start the race. 

Theron said it was "special" to attend Patrick's finale. Patrick is the only female driver to win a pole and lead laps at the Daytona 500.

 "As a woman, that just seems pretty incredible," Theron said. "For me to be able to witness her last race, that feels very special. The girl in me is secretly obviously cheering for her. I just love that even my kids were just impressed that girl was racing cars today, too."      

Theron also busted on "Italian Job" co-star Mark Wahlberg for puking during driver training for the movie. She also laughed as she recalled a trip to Daytona as a teen where she got drunk and then went skydiving.
