I'm tempted to say Fred Durst, but calling him a rock star is a bit of a stretch.
And Liam Gallagher - it's always the people with the least actual ability that have the most ego.
Liam Gallagher has never been a great singer - and he's only gotten worse over the years. He was the reason Oasis split up. His 2nd band broke up because they weren't doing very well - and he still acts like a massively egotistical rockstar.
Recently he's just been lashing out at Noel on twitter because High Flying Birds are so successful. Saying " he was planning his solo album whilst oasis were still together "
and " songs on the first HFB album were written when he was still in oasis "
As if either of those things are somehow abnormal ?
I want Liam to write and record his own solo album and see how well that does before he starts dishing out abuse to other, more talented people out of jealousy.
Noel, on the other hand - whilst he has said some poor things in the past ( some of which he apologised for ) - his arrogance is mostly tongue-in-cheek and in one-on-one
interviews is pretty down to earth and humble. He has also notably matured over the years, he's 47 now and seems pretty laid back whilst Liam is in his 40's too and still acts
like a 21 year old. Noel is also hilarious. But get him on a TV show with a big audience and the pretend arrogance comes out.
He's said in the past that you never know how long your career in music will last so he's just having fun with it.
