MMA star and the lead of the Irish shot Haywire, Gina Carano is in negotiations to join the cast of Fast Six, says Heat Vision.

Carano got some really strong notices after the Steven Soderbergh action flick, and quickly picked up the lead role in the action thriller, In the Blood. She will shoot her part in Fast 6 first, and then move on to the John Stockwell directed flick. All of the main cast are back for Fast 6 are returning, as is director Justin Lin. Breakout from Fast 5, Dwayne Johnson, will quite probably have a bigger part this time too - given how well he went down after the flick grossed $600 million worldwide.

Shooting is set to begin in the next couple of months for a release next summer.
