The "Safe Haven" actress had $100,000 worth of jewelry -- reportedly gifts from boyfriend Ryan Secrest -- stolen out of her Mercedes at a Hollywood apartment complex.
According to TMZ, Hough returned to her car Friday night after visiting with a friend only to find the door wide open and her jewelry missing.
One of the three items missing was supposedly a $50,000 watch.
Law enforcement officials said there were no signs of forced entry. It's unclear if Hough left the door open for thieves to help themselves.
