Justin Bieber has thanked Kanye West for attending one of his 'Purpose World Tour' gigs and admitted the US rapper is one of his ''inspirations''. Justin Bieber has thanked his ''inspiration'' Kanye West for attending his show last night . The Sorry hitmaker was delighted to see the US rapper and his wife Kim Kardashian West enjoy a date night at Los Angeles' Staples Center to take in part of his Purpose World Tour, and admitted he put on a big performance for the 38-year-old star. He tweeted: ''Shout out to one of my inspirations @kanyewest for coming to the show tonight. Had to go big. #PurposeTourLosAngeles night 2 (sic)'' Kanye - who recently admitted Justin's hit 'What Do You Mean' was his favourite song of 2015 - took his wife Kim along to the gig and appeared to enjoy himself as the reality TV star posted a video of her significant other dancing along to his tunes on her Snapchat account. She also shared a selfie of the pair looking every inch a loved up couple at the show. Justin's thanks to Kanye comes just a few days after he mocked the rapper following his Staples Center gig on Sunday. The pop star grabbed the microphone at the 1 OAK nightclub in LA after another of his successful shows, but before giving the crowd some advice he joked: ''I'm not gonna give like a 30-minute speech. I'm not Kanye West. I love Kanye. I only got a little bit to give though.'' He then said: ''All I'm gonna say is let's have a good night, let's enjoy ourselves. Let's be ourselves. I think the thing the world struggles with most is just being ourselves. I think people hate on people that just are themselves. ''Maybe I'm drunk. Maybe I'm just speaking real s**t. But I feel like a lot of the reason why so many people hate on me is cause I'm just myself.''..
