Sean Penn introduced ex-wife Madonna to his daughter on Thursday night (17.09.15).

The Oscar winner, who divorced the 57-year-old singer in 1989 after four years of marriage, took Dylan Penn, 24, to cheer her on from the front row during her 'Rebel Heart' concert at New York City's Madison Square Garden before taking the model backstage to meet the star.

And a source told E! News: ''He introduced Dylan to Madonna. It was the first time they had met.''

The 'Mystic River' star, who divorced Dylan's mother Robin Wright in 2010 after 14 years of marriage, was also captured on camera by several fans smiling widely while Madonna performed her classic track 'True Blue' during the gig, which she dedicated to him when it was released in 1986.

Sean asked Dylan to attend the gig after receiving a personal invitation from Madonna, according to the insider.

The 54-year-old actor, who has been single since splitting from former fiancée Charlize Theron in June, previously revealed he and his first wife are still ''very friendly.''

Speaking last year, he added: ''Initially, in a divorce, you kick and bite about the other person. But finally you're looking at your failures to that person, to a marriage, to a friendship, to yourself during that time as well. Because no matter what the other person was or wasn't, for better and for worse, it really has so little to do with the growth you need to find better circumstances. Almost exclusively it has to do with your own stuff.''
