The 47-year-old rocker has become known for his long-running feud with his older brother and rival Noel Gallagher, which has seen Liam brand his sibling as a "potato", as well as blame him for the split of their band Oasis, and accuse him of preventing a reunion of the 'Wonderwall' hitmakers.But now, Liam has confessed that whilst he views himself as "extraordinary", he also knows he can step out of line from time to time.He said: "People know who I am. I am extraordinary but I can also be a bit of a knob - I know all of that."The 'Shockwave' hitmaker recently apologised after he allegedly threatened Noel's wife Sara MacDonald in a message sent to Noel's 19-year-old daughter Anaïs.And although he's vowed to stop mentioning Noel's family on social media, he won't stop teasing his brother.He added: "He's got this impression he's special but if you asked him to play his new songs on acoustic guitar it sounds f***ing shocking, in the wrong sense of the word. He's not on top form, but I'll let him keep doing his thing."Liam says it's a "shame" that Oasis split following a row between the two brothers in 2009, but says he still has "hope" they'll reunite one day.The 'One of Us' singer explained: "It's a shame and really sad that the group split up but while we are still alive there's hope. Even if one of us is making a stupid disco, at least one of us has stayed the same."Whilst he waits for the band to get back together, Liam is enjoying a successful solo career but says he isn't planning on changing his career path any time soon.Liam - who is engaged to his long-term girlfriend Debbie Gwyther - told the Daily Star newspaper: "I never want to be an actor even though I'm beautiful enough to be one. I like to be myself 24 hours a day, seven days a week, I don't need any script. I'm happy being me."credit: www.music-news.com
