Rumours have circulated that his bromance with kickboxer Badr Hari might be more than platonic with a French sports commentator saying Ronaldo had been heading to see Hari's place in Morocco for some "cuddles".
Shayk is now dating Oscar-nominee Bradley Cooper.
The pair have been dating for a few months and things seems to be going well between the pair.
In a clip from October the pair teased fans about a collaboration.
"Hi guys, we've finished photo-shooting, it was amazing filming with Alessandra, she is fantastic, she does a fantastic job, Christiano says in the cli," he said. "We are not going to say what we did because it's a secret, we hope you are going to like it."
"I had a great time with you," Ambrosio replies. "You're an amazing person, a super-nice guy and I hope you guys have fun and it's a top secret project so you're not going to find out."
