Liam Gallagher dedicated 'Paper Crown' to his brother Noel at his London show on Thursday night (07.12.17), subtly hinting the track contains jibes about his older sibling and bitter rival.
The former Oasis frontman - who sold-out the 10,000 capacity venue - appears to diss his sibling and former bandmate on the chorus of the ballad with lines such as, ''now you're feeling the fear'', which could be interpreted as Liam saying his brother fears him doing better than him with his solo music.
Before performing the track from his debut solo LP 'As You Were', Liam said: ''Thank you very much. I'd like to dedicate this one to my brother.''
The 'Wall of Glass' hitmaker has previously used his music to attack his family rival, who he has barely spoken to since Oasis split after a backstage bust-up at a show in Paris in 2009.
On 'BE', the second album by 'Beady Eye' - the band he formed with the other final members of Oasis in the wake of the break-up - Liam penned 'Don't Brother Me' which contained lyrics mocking Noel's solo career and his friendships.
And it was previously speculated that his solo album tracks 'Greedy Soul' and 'You Better Run' contain swipes at Noel.
Apart from the odd utter thanking the crowd, Liam remained focus on nailing his 18-song set list, which saw him play 10 Oasis classics, including their first ever song 'Supersonic' from their 1994 debut LP 'Definitely Maybe'.
The 45-year-old rocker brought the house down closing with a crowd-led rendition of fan favourite 'Wonderwall'.
Liam drew in a star-studded audience at his biggest headline solo gig of the UK tour.
One Direction star Louis Tomlinson posed for pictures with fans, which circulated on Twitter, and 'Celebrity Big Brother' star Heavy D was among those watching their idol perform.
After playing to the masses at Alexandra Palace, Liam has a day off before heading to Edinburgh on Saturday (09.12.17), where he'll busk for Social Bite's Sleep in the Park event to help tackle homelessness in Scotland.
The 'Songbird' songwriter will be joined by the likes of Deacon Blue, Amy McDonald, Frightened Rabbit and more performing as several stars and members of the public take to the city's West Princes Street Gardens to sleep rough for the charity.
