Ryan's alleged new girlfriend Whitney Heard.

Ryan and Mandy, 30, wed in 2009 after one month of dating. She filed for divorce back in January.

"They really were just two very different people," another source alleged. "He's such an introvert, and she may not want her life out there every day, but she's so sweet and friendly and social. Total opposites."
