Former BEVERLY HILLS, 90210 star Jennie Garth burst into tears live on American TV on Monday night (01Oct07) after taking a tumble on the dancefloor. The actress, a contestant on TV show Dancing With The Stars, was dragged to the floor by her professional dancing partner Derek Hough after he tripped over her dress. And now Garth fears the trip will cost her a place on the show. Backstage, the upset star said, "This was not what we planned. We had one in dress rehearsal and it went fine." As WENN went to press it was not known if Garth and Hough had been voted off the show.
