Ashley Judd and her estranged husband Dario Franchitti had a turbulent marriage.

The Dolphin Tale actress and the Scottish racing driver recently decided to end their 11-year union but according to friends, the split was not a huge shock. 'They can be having a drink or dinner and all of a sudden sparks will fly, and they will be fighting over something that was said in their group of friends. Then it would stop and everything was fine between them," a source told people.

However, some pals were surprised as they believed Ashley, 44, and Dario, 39, who got engaged in December 1999 and married in December 2001, at Skibo Castle, near Dornoch, Scotland, were happy together because she was always so supportive of his career. Another insider added, "When he was introduced, or got a good pole position she yelled and waved her hands in the air and was there to support him in a big way. He is not that outgoing but it seemed cute and like a nice thing for a high-profile actress to be so there for her husband."
