Cristiano Ronaldo started his day in the sun by getting oiled up real good … by his mom.
Cristiano’s still on vacay with his fam in Ibiza — and moms was NOT shy about slathering tanning oil all over the back of his $200 million legs Wednesday on their yacht.
Looks like she avoided too much contact with his left leg … where he’s nursing the MCL injury that took him out of the European Championship.
Tight family — gets ya through the hard times.
