Getting rid of the Beer belly! Justin Bieber goes for a run with crop top-wearing protégée Madison... but leaves her in his wake

He was solely responsible for launching her professional career.

And it looks like Justin Bieber also has a hand in Madison Beer's daily fitness regime too.

The duo went for a run together in Los Angeles on Monday.

Fit: Justin Bieber and Madison Beer went for a run together in Los Angeles on Monday

Left behind: His 17-year-old protegee couldn't quite keep up

Justin looked super-fit in a pair of Nike trainers, running leggings, and sports shorts.

On top he showed his new found allegiance to English Premiership side Arsenal by wearing their third choice strip. 

The 17-year-old Beer meanwhile was clad in a midriff-baring sports bra, which she paired with yoga pants and a pair of Converse.

The starlet seemed to be wearing a fair bit of make-up for the run, partially tying her gorgeous brunette main back in a long braid.

Fan: Justin likely picked up his soccer strip after a trip to Arsenal's homeground, the Emirates Stadium, in October

Star treatment: While on the London stop of his Purpose World Tour, he enjoyed a tour of the training ground

Her choice of bag - a low-slung leather purse - was not the usual fare one normally sees joggers employing, even in Hollywood.

Despite being five years his junior, Madison was no match for the super-fit Bieber, who sprinted off and left her in his dusty wake. 

Just in case no-one recognised him, Justin even had his jersey personalised with his name on the back.

Get on trend like Madison with fringe sneakers

Madison Beer may be working out but she's still a stylish gal. The Bieliber protege was snapped jogging in an an all black look consisting of a crop top and leggings with these on-trend fringed Converse sneakers.

An easy way to dress up work out wear and a great casual option while on the go, high top sneakers are not just for the basketball court anymore.

So many designers have re-imagined them from Lanvin to Louis Vuitton. But nothing is as classic as a pair on Converses. So head to Macy's now to get a similar suede version to Madison's. Or if you're not sold on the fringe, check out our edit below.
