Wait! Wizkid did not buy the world's most expensive champagne he popped for his birthday, Liam Payne did

His band One Direction are officially the highest-earning youngsters in the music industry, and he took home a whopping £5million earnings in the last year alone. And Liam Payne was evidently feeling very generous indeed on Tuesday night when he reportedly treated a pal to a bottle of champagne, worth a staggeing £1.2million. Dubbed 'the world's most expensive champagne', the kind-hearted 19-year-old is believed to have made sure his Nigerian musician pal, Wizkid, had the best 24th birthday a boy could wish for by splashing out on a bottle of Tast Of Diamond at London's Funky Buddha nightclub. In a snap posted on the Twitter page of luxury designer Alexander Amosu, the Wolverhampton-born singer was seen pouting away into the camera as he poured a glass of bubbly for his pal.

Alongside the snap, he wrote: '@wizkidayo & Liam (one direction) enjoying taste of diamonds @goutdediamants at his birthday party. Launching in NIGERIA end of this month with this Swarovski Diamond bottle edition.'And it would appear generous Liam had made his friend's night, with Wizkid tweeting: 'What a night! Thanks to all that made that happen! Had fun!'
