JUSTIN Bieber looks ready to yell “Yee-ha!” and lob a lasso at a rogue buffalo with his latest bizarre outfit, channelling the Wild West on the streets of New York.

The 23-year-old pop star went full Cowboy as he wore a white Stetson and chewed on a straw while out and about, after it was announced he’s joined Ariana Grande’s charity concert in Manchester.

The One Less Lonely Girl hitmaker matched his Stetson with a gold baseball jacket and shorts, as well as a pair of his own leggings branded with the word “Bieber”.

The grinning superstar was also carrying a spare pair of shoes, suggesting he needed one pair for a workout or a jog.

After remaining firmly in the pop and dance genres since he started out as a teen singer, Bieber’s bold choice of hat hints he may be going country.

Justin wouldn’t be the first pop star of his generation to go country as Miley Cyrus returned to her genre roots recently too.

It’s not yet known what tracks Bieber will sing at the Manchester bombing tribute concert, where he’ll perform alongside Miley, Coldplay, Katy Perry, Take That, Niall Horan, Pharrell Williams, Usher and Ariana herself.

Madonna is also rumoured to be performing at the show, which follows Liam Gallagher’s solo tribute concert last night.

Bieber is bound to bring a sense of fun to the morale-boosting gig, after forgetting his own lyrics to Despacito on stage and singing “Doritos” instead.
