X Factor judge Tulisa Contostavlos has denied allegations she abused airline staff on a flight to Spain.

It's claimed she got into a row when her N-Dubz bandmate Fazer was asked to turn off his phone.

A British Airways spokesman said they had a record of an incident on a flight from London City to Palma involving passengers using mobile phones.

He said: "A lady in the party who wasn't using her phone was abusive towards the crew."

23-year-old Tulisa used her Twitter account to write: "I completely deny that I was abusive to airline staff on our flight to Majorca a few weeks ago."

She continued: "My PA had a disagreement with staff over his mobile phone but I categorically did not swear at the steward. I'm disgusted that someone would make this up about me!"

Tulisa was travelling with her N-Dubz bandmates to play a gig on the island.

A spokesman for the band has also issued a denial about N-Dubz splitting up.

It read: "N-Dubz have 100% not split up. They are concentrating on solo projects for the time being, but remain committed to N-Dubz as a group and will continue performing and recording together. They are completely supportive of each others solo projects."

Dappy is due to release his debut solo single No Regrets while Tulisa is continuing with her role as a judge on the current series of The X Factor.
