Kristi Yamaguchi is devastated after priceless items were stolen from her trailer during a recent stop on the Dancing With The Stars tour across the U.S.The Olympic champion figure skater - who won the 2008 series of the TV dance competition - left her valuables in a van, shared by her co-stars Mark Ballas and Derek Hough, while visiting in Roseville, Minnesota to take part in a cancer benefit.Thieves reportedly took passports, diaries, photos and thousands of dollars worth of electronics during the break-in on Saturday.Yamaguchi says: "I feel so bad. These guys (the dancers) came in for a good cause to help out - and it's not starting out so good. It's more emotional because there are so many memories."A $5,000 reward has been offered for information leading to the return of the items.
