Julianne Hough's jewelry was stolen from the backseat of her own car.

Julianne Hough's stolen jewelry reportedly was priced at about $100,000.

The country singer and 'Dancing With The Stars' champion had been given the jewelry by boyfriend Ryan Seacrest.

The jewelry theft incident occurred in Hollywood on the night of Friday, March 8, while Hough was visiting a friend, TMZ reported.

Julianne Hough reportedly left three pieces of jewelry in her car after parking the Mercedes Benz in a lot outside a Los Angeles apartment complex.

Law enforcement officials reported no signs of forced entry. It's unclear why Hough left the doors unlocked.

'Safe Haven' star Julianne Hough returned to her car several hours later to find her doors open and the jewelry missing.

A TMZ source says one of the items was a $50,000 watch.

Julianne Hough is scheduled to star in Diablo Cody's 'Paradise,' a film about a woman who loses her faith after being burned.

Russell Brand and Octavia Spencer will also appear in the film.

'Paradise' is expected to release in September 2013.
