Pete Doherty and ex-fiancée Kate Moss have maintained a good relationship since they split-up more than a decade ago, with them even taking part in an annual ritual.
The singer, 43, and the model, 48, started dating after meeting at a birthday party in 2005, with the pair having an on-off relationship over the following two years.
They were even planning to get married at one point, with Pete having introduced Kate as his fiancée at a gig in 2007 - just months before they ended their romantic relationship.
The former couple have both since moved on, with Pete having married partner Katia de Vidas - the keyboardist in his new band The Puta Madres - in a ceremony last year.
There doesn't appear to be any hard feelings between Pete and Kate though, with him revealing recently that they have kept in touch and send each other Christmas cards.
The Libertines frontman said that his ex is happy for him and supports his endeavours, stating: "She's really supportive and enthusiastic about everything I'm doing."
He said that they remain in contact with each other - despite it being understood that their split was acrimonious - with him adding: "We get a Christmas card every year."

Pete dated the supermodel at the height of his fame and notoriety. He was once known as one of music's biggest junkies, though has now been clean for more than two years.
He credits musician Frederic Lo as lifting him out of the darkness during his battle with addiction, after being encouraged to cover a particular song whilst giving up "hard drugs."
The singer said: "Word got to me that this fella wanted me to cover a song by French singer Daniel Darc. It was called 'Inutile et hors d'usage,' which means 'Useless and all used up'."
Discussing the impact of the track, Pete commented: "I got really emotional when he played it to me, it really hit home. I was giving up hard drugs and feeling f***ed really."
He credits Frederic as having helped him address his issues, with the pair having now written an album together, the Fantasy Life of Poetry and Crime - released last week.
The Fantasy Life of Poetry and Crime - by Peter Doherty and Frederic Lo - is out now.
