According to Heat, Welsh band Lostprophets said that the 26-year-old singer invited her family and friends along to share the special VIP passes.
The 'Last Train Home' rockers also criticised event organisers for not allowing their families to receive any free entries.
However, Cole's PR company today posted on Twitter: "Dear Lost Prophets, Cheryl did not have any family or friends at 1BW. Maybe Radio 1 thought you weren't worthy of VIP tickets (sic)."
Justin Bieber, Rihanna and Dizzee Rascal were also among the performers at the concert.
