Prince Frederik posed for a solo Christmas picture as his wife Princess Mary jetted off to Australia for the festive period.
This comes as the Crown Prince of Denmark was accused in the Spanish press last month of having an affair with a Mexican socialite, which the latter strongly denied.
Genoveva Casanova, the Mexican socialite, said she "categorically" denies any suggestion she was romantically involved with Frederik after they were photographed together in Madrid.
The Danish Royal Family has not yet commented on any of the allegations.

His wife, Crown Princess Mary, was instead pictured at Sydney airport with the couple's 12-year-old twins Prince Vincent and Princess Josephine.
Mary was born in Hobart, but she married the future King of Denmark in 2004.
