Gaga Daily, a fansite dedicated to the talented performer, shared a picture of Lady Gaga that is identical to a tattoo on Carino's upper arm.
Fans of the 31-year-old entertainer were quick to compliment the tattoo and praise their relationship.
One fan wrote, 'I love the way he supports her in all she does and is always with her. I really love seeing how in love they are and how happy she is now. She needed someone like him in her life.'
However, there were a few displeased with the bold gesture.
One social media user wrote, 'Not cool. I think he’s a stalker.' With another adding, 'Am I the only one being creeped out by that?'
The couple, who only began dating earlier this year, became engaged in early October.
It has been reported that the duo got married in a secret ceremony shortly after, but have never made a formal statement.
