Joan Collins gives the bottom line on Madonna Met Gala outfit

Dame Joan Collins has warned that Madonna’s sons might get teased after the pop star bared her derriere at the Met Gala.

The actress, 82, recalled how embarrassed her son was after she appeared in lingerie in her film The Stud, and said Madonna’s children might feel the same way after their mother arrived at the fashionable event in a bottom and breast-baring Givenchy ensemble.

Asked what she thought of the photographs of the 57-year-old pop star on ITV’s Good Morning Britain, Dame Joan said: “I thought it was a costume party or a Halloween look, but it’s the Met Ball, which is supposed to be one of the most glamorous and fashionable events, and I thought the bottom coming out was a bit over the top.”

She added: “It reminded me of the time when I was in a movie called The Stud and pictures of me came out, and I was wearing a basque and stockings, and when I went to my son Sacha’s school to meet the headmaster when he was 16, he was very embarrassed.
