How To Be Proper Exes 101:
The former spouses showed their mutual love for one another Tuesday night, posing together at Madge's New York party for her #SecretProjectRevolution at the Gagosian Gallery.
While we were personally enjoying her performance, we're sure Sean was glued to her every move too, especially after seeing this friendly photo!!
Back in 2012, we heard reports of Sean's undying infatuation for Her Madgesty, and though she seems happily in love with (fiance?) Brahim Zaibat, it makes us giddy knowing exes can still respectfully adore each other after all these years!
In case you haven't been keeping count, they were married in 1985 and divorced in 1989. So yeah, to still stay in touch — we'd say these two deserve lifetime achievement awards for maturity, LOLz!
