Campbell relishing role in 'Ugly Betty'

English supermodel Naomi Campbell has been speaking about how she hit a ball so hard while working on her cameo role in 'Ugly Betty' that it broke in half.

She was given a crash course in softball for her part - and despite the minor hiccup she picked up the necessary skills speedily.

Campbell heaped praise on the cast and crew and said she had had a "fantastic" time filming the show, which has been hugely popular on both sides of the Atlantic.

She donned a sports outfit and was caught on camera towering over some of the cast during filming in Los Angeles.

She joined 'Ugly Betty' star America Ferrera and other cast members, Becki Newton and Michael Urie, on a pitch to film the episode Jump, which will air in the US on May 22.

Campbell said of the filming: "I had a fantastic day on set. The cast and crew were so lovely.

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

"The coach said he had never seen anyone pick up the game so quickly!"

Campbell previously said of her 'Ugly Betty' part: "I'll play a loony who loves to shop and can't find a man. I like that sort of role."
