The Argentinian model split from Price last October after being in a relationship with her for almost two years.
Price and Hayler married in January just weeks after they got engaged, reported Contactmusic.
Asked if he thinks Price's marriage will stand the test of time, Penna said, "No. It won't last. I give it a year, tops."
Price, 35, and her third husband have since had a baby together, son Jett Riviera who is currently being cared for in a European hospital after he had to be delivered eight weeks premature.
"She told me so many times she wanted to marry me, but I didn't want to marry her. She always said she wanted a baby with me, but I didn't want one. She was not someone I wanted to start a family with. Her life is a business and I don't want my life to be like that," he added.
