Last January, the still-gorgeous model opened up to ET's Nancy O'Dell about her dating life -- namely, how it was hard to date guys in her own age group
. "It seems like during this period that most of the guys are like 38, 39, 42, like that sort of age group," Brinkley revealed. "It's funny because I think that at that age they have nothing to prove. They're very confident and do just what they want to do. [With] men my age I feel quite invisible to them."
