The couple had been aboard their luxury £5.5million yacht, sailing from the Italian Riviera to Ibiza on an 11-day cruise.
On what appears to have been a beach break, the Ronaldo family posed for a picture on the sand.
The scenic spots of St-Tropez, Monaco and Majorca were all visited as they made their way to Ibiza.
But the fun is over for Ronaldo as he marked his return to Juve training.
The Italian kings worked out under new coach Andrea Pirlo for the first time since he replaced Maurizio Sarri.
At one point, Ronaldo flashed a thumbs-up to camera as he stood near his new boss.
Pirlo has laid down a marker in Turin having released Blaise Matuidi, Sami Khedira and Gonzalo Higuain.
Higuain’s departure has left the managerial novice looking for a strike partner for Ronaldo & Co.
According to Mundo Deportivo, Luis Suarez and Juve vice president Nedved have been locked in discussions over a potential switch.
It comes after Suarez was told by new Barcelona manager Ronald Koeman that he could leave.
That then sparked a furious reaction from Lionel Messi, who stunned Nou Camp bosses by handing in a transfer request.
Manchester City lead the race to sign the 33-year-old Argentine, but it is understood Juve have at least enquired about the potential cost of a transfer fee.
