Don’t let anyone tell you that gorgeous Christie Brinkley doesn’t have a (kind of mean) sense of humor!
The 61-year-old went to a concert given by her ex-hubby Billy Joel — wearing a T-shirt emblazoned with the name of her new guy, John Mellencamp!
She even visited her former spouse backstage at New York’s Madison Square Garden with son Jack and daughter Sailor for a little get-together.
The supermodel and the singer were married for nine years before splitting in 1994.
That’s a lotta nerve!
