According to dailymail.co.uk, Glenn in her first interview after the relationship became public said: "I'm a very frank, realistic person. It's a multifaceted thing. Neither of us is blind and, of course, it is physical but it isn't only or mostly about looks."
Along with the 29 year age gap, there is also a height difference between the couple. Rushdie is five feet 10 inches and Glenn is six feet four inches in heels.
Glenn said: "I think he is a genius, genius novelist and he thinks I am smart and that's the biggest thing, the aphrodisiac. With other men, I have had to hide that side of myself because I felt if I came off too smart, I'd be ostracised. This is a good old-fashioned romance but the attraction started as a meeting of minds."
