Since marrying model Hailey Baldwin, Justin Bieber has massively cleaned up his actCredit: BackGrid

A decade of unforgivably poor haircuts, even worse tattoos and brattish behaviour on an epic scale marked his card as the man to avoid at every showbiz event.

The bloke’s wildest phase even saw him keep a pet monkey — which has reportedly never been the same since he abandoned him in Germany five years ago.

It now lives in a zoo where experts described it as “frightened and disorientated”.

Who wouldn’t feel like that after a few months with Justin, just ask Selena Gomez, Sofia Richie and a host of short-lived infatuations who briefly found themselves as the wannabe Princess in the Prince of Pop’s bewildering pantomime.

So it’s even more of a miracle that, despite countless arrests, he has finally posed up for a mugshot worth having — alongside his beautiful new bride, Hailey Baldwin.

In black and white snaps from the photo booth at their swanky reception, Justin looks a new man, with a sensible short back and sides and a sharp suit — pop’s most precocious wild child has actually grown up.

Unaccustomed as I am to praising Bieber . . . he actually seems all right.

Sure, he’s still banned from China after the government there decided they don’t want to let in “talented but badly behaved entertainers”, and photographs of him skinny dipping with at least two stunning models will live for ever on the internet, but at 25, Biebs has settled down.

Justin drew a line under his years of debauchery at a gorgeous chapel at the luxurious Montage Palmetto Bluff hotel in South Carolina, US, in front of their parents and family — plus 140-odd pals.

They included Ed Sheeran, Kendall and Kylie Jenner and Katy Perry — who were treated to champagne bearing the couple’s names in bejewelled bottles.

But despite their best efforts, even Kylie and Kendall struggled to upstage the beautiful bride with a pair of figure-hugging sparkling gowns . . . they’ve both been romantically linked to him too, by the way, but I’m sure nobody worried about a little thing like that.

Justin’s former flames have had plenty of time to come to terms with losing him after he quietly formally married Hailey late last year at a New York courthouse — but no fairytale wedding would really be complete without a speedboat ride, a touching nod to Justin’s naff past.

Sure, he’s got a lengthy rap sheet of showbiz crimes, and an ego that could sink a battleship but, for the first time, I actually want to be his mate.

JUSTIN’s musical director, Dan Kanter, played guitar during the ceremony. There was a string quartet to greet the guests as they entered the reception before Grammy award-winning singer Daniel Caesar performed live.

And then, like at all good weddings, Justin and Hailey had a classic disco to end the night.

EACH guest was given a personalised bottle filled with a soft drink to keep them going on the way to the church.

Cocktails were served after the ceremony and when they got to their table for a three-course meal there was a crystal-encrusted bottle of Moet & Chandon champagne. Free booze flowed all night.

After they arrived in South Carolina guests were given personalised T-shirts and they could have a go at cycling and shooting.

After the rehearsal dinner the couple had booked out a whole bowling alley and they also put on a screening of their favourite film, 2004’s The Notebook, with an ice cream and cookies feast at midnight.
