"Speaking of Katie Couric, the TV personality has had her own romance with a younger man! The 55-year-old dated Brooks Perlin, who's 17 years younger than her, for five years until they split in December. At the time, a source told <a target=""_blank"" href=""http://www.usmagazine.com/celebrity-news/news/katie-couric-splits-with-brooks-perlin-20111312#ixzz28HHSZBGD"">Us Weekly</a> that the numbers factored into the breakup. ""Brook's a nice guy, but it was inevitable because they had different priorities and perspectives, and their age difference made it a challenge, too,"" the source said. Couric's current beau of several months is closer to her age, so perhaps this one will work out? John Molner, the head of mergers and acquisitions at an investment bank and securities firm, is 49.
