The couple wed in Savannah, Georgia on Tuesday, just a month after confirming their engagement.
The couple were spotted together again on the musician's recent tour after announcing their break-up in August 2008. They initially began dating in late 2007.
"I am very happy," Mandy told Bonnie Hunt in an appearance on "The Bonnie Hunt Show" shortly after the engagement news broke.
The singer-actress is preparing for the May 26 release of her next album, "Amanda Leigh," while new husband Ryan is set to release his first book, "Infinity Blues," in April.
