For the same reason none of Liberace's or Elton John's ex-girlfriends have never come forward, there were none. Michelle is appears to be an angry woman which may be an indication that Barry has no interest in taking care of his woman if you know what I mean.
Elton John was married to German recording engineer Renate Blauel in 1984 and they divorced four years later.
Uh... actually there were, even one who tried to trap him into marriage by falsely claiming she was pregnant (inspired the 1975 song "Someone Saved My Life Tonight").
His (ex) manager John Reid introduced him to the "gay lifestyle" by taking him to bed. Still, Elton married a woman in Australia in the 1980s.
Actually, Elton John was married to a woman at one time! Of course, that was a long time ago. Then he was divorced from the lady awhile back, and ‘came out’ just after, I think!
In the case of Elton John you are wrong there is not only a ex-girlfriend there is an ex-wife. And yes she was a she.
Can't remember her name but she was a pickle heiress. < place your own joke here >
