Liam Gallagher welcomed the "Wembley vibes" as he performed there ahead of Oasis' seven dates at the London stadium in 2025.
The Manchester rocker performed a short set at the football venue before Anthony Joshua met Daniel Dubois in the boxing ring.
His performance, after the long-awaited Oasis reunion was confirmed on August 27th, included the songs Rock 'N’ Roll Star, Supersonic, and Cigarettes And Alcohol.
The last time brothers Noel and Liam performed together was on August 22 2009 at V Festival in Staffordshire.
Among the famous faces ringside were former heavyweight world boxing champion Tyson Fury, MMA boxer Conor McGregor, former boxer Ricky Hatton, Spice Girl Emma Bunton and Love Island presenter Maya Jama.
Liam came on to a massive cheer and and said "yes Wembley vibes in the air", during his performance as the warm-up to the main event, in front of a record-breaking 96,000 crowd.
His string of 19 UK and Ireland Oasis dates with Noel have all sold out, including two extra Wembley shows after the furore over ticket sales and inflated prices.
Oasis said they were unaware that dynamic pricing, which led to tickets selling for more than double the original price, was being used on Ticketmaster, and blamed the situation on "unprecedented demand".
Ticketmaster has previously said this was down to the organiser of the sale, not its website.
This year marks 30 years since the band released their debut studio album Definitely Maybe, which sailed to the top of the UK charts earlier in the month, bolstered by the release of a deluxe edition celebrating its anniversary.
