The 44-year-old singer blasted his sibling on Twitter for not joining him at the gig on Sunday.
He later apologised to fans on social media saying: ‘Manchester I’d like to apologise for my brother’s absence last night. Very disappointed. Stay beautiful, stay safe.’
Liam then added: ‘Noel’s out of the f**king country, weren’t we all love. Get on a f**king plane and play your tunes for the kids, you sad f**k.’
The brothers famously fell out after Noel left Oasis following a massive row in 2009.
Liam was joined by Coldplay frontman Chris Martin on a rendition of Oasis’ ‘Live Forever’ at Emirates Old Trafford.
He also performed ‘Rock‘n’Roll Star’ and his new solo single ‘Wall of Glass’.
Afterwards, he tweeted: ‘What an amazing night last night. Pure love vibrations. Nobody comes close to Manchester.’
The singer had flown in from a gig in Germany to surprise the 50,000-strong crowd.
Miley Cyrus, Pharrell, Katy Perry, Justin Bieber, Niall Horan, Little Mix, Take That and Robbie Williams also performed last night.
The concert, which paid tribute to the 22 people who were killed at Ariana’s gig last month in the city, raised UK£2 million for the We Love Manchester Emergency Fund.
