Naomi Campbell learned to play softball for her cameo role in U.S. TV show Ugly Betty.

The balding catwalk queen plays "a loony who loves to shop and can't find a man" in the upcoming second series finale which will be aired in the U.S. on 22 May.

Campbell will be seen taking part in a softball match which pitches a team of models against the show's regular cast.

And Campbell was taught how to play the game before filming and discovered she has a very powerful swing.

She says: "I was given a crash course in playing softball and at one point hit the ball so hard it actually broke in half!

"I had a fantastic day on set, the cast and crew were lovely. The coach said he had never seen anyone pick up the game so quickly."

Campbell follows in the footsteps of Victoria Beckham in appearing in the programme. Posh Spice appeared on the show in November when she played a bridesmaid to Vanessa Williams' catty fashion boss character, Wilhelmina Slater.
