Princess Mary of Denmark was caught in an awkward moment during a televised state dinner when she apparently noticed the Finnish president's husband staring at her cleavage.
Video shows First Gentleman Pentti Arajarvi gazing towards the Tasmanian-born princess's chest during the lavish royal dinner, hosted by the Queen of Denmark on January 15.
The First Gentleman quickly looks away when he sees Princess Mary spot him.
The princess puts her hand over her chest and tries to adjust her dress, but still manages to keep a smile on her face.
Princess Mary married the Crown Prince of Denmark Frederik in 2004, after meeting him in a pub in Sydney during the 2000 Olympics.
Arajarvi's wife Tarja Halonen is Finland's president and the country's first female to hold office.
