Lourdes Leon has got a tattoo in tribute to her parents.

The 19-year-old star - who is the daughter of Madonna and Carlos Leon - showed off the inking on her knuckles of the word's 'mom' and 'dad' on her brother Rocco's Instagram account.

However, Rocco didn't seem too enthused by the new ink, captioning the image simply: ''B M T (sic)''.

It is no surprise that Lourdes got the permanent inking dedicated to her parents after the 57-year-old singer previously admitted the pair are so close that she fell into the ''deepest depression'' when Lourdes went off to college.

She explained: ''My sister said it to me when her son went away. I was like, 'Oh my God, you're being so dramatic.' She was, like, bawling and bawling.

''And then my daughter left me, and I fell into the deepest depression. And I'm always so happy when she calls me and she says, 'Mommy, I miss you' or 'I need you to rub my head.'''

And the 'Rebel Heart' hitmaker also insisted she would never stop her daughter from drinking or doing drugs but just encourages her to make ''wise decisions''.

She shared: ''I just ask my daughter to make wise decisions and to do things in moderation and to try not to mix her alcohol.

''I am not going to say, 'No, don't do it' because that is just absurd. And it is not fair. Yeah, I did it.''
