The forward recently signed off for the season with club side Al Nassr after his shock move to the Saudi Pro League in January.
It was a tough season that saw Al Nassr miss out on title glory and now the 38-year-old is enjoying the rest and recuperation ahead of a first full season with his new club.
Ronaldo took to Instagram on Thursday to post images of his family holiday with partner Georgina Rodriguez and children Cristiano Jr, Eva, Matteo and Alana Martina.
In one picture, a lean looking Ronaldo and Georgina are cosying up together in their swimwear as they appear to quash all rumours of a relationship breakdown between the pair.
The former Manchester United star is later seen with a drink in hand on board a boat.

He is seen sporting his signature six-pack as he continues to maintain his incredible fitness levels into his late 30s.
Ronaldo was unable to help his teammates claim the League title last season, losing out to eventual winners Al-Ittihad.
