Denmark's Princess Mary has had an awkward moment on live TV when she caught a state guest staring at her cleavage.

The video of the incident shows the Tasmanian-born princess sitting next to Finland president’s husband Pentti Arajarvi who is staring at the her chest during a lavish royal dinner.

The First Gentleman quickly looks away when he sees Princess Mary spot him.
