The singer, who replaced Kelly Rowland back in June, wants to remain close to boyfriend Lewis Hamilton during the X Factor live shows, The Sun reports.
She will apparently attend his Grand Prix race meetings in the likes of Abu Dhabi and Brazil, at a cost of at least £50,000 a time, to keep their relationship on track.
"Lewis will sort some flights out for her, but she's booking some herself and they're eye-wateringly expensive," a friend said.
"If she has any cash left at the end of this I'd be surprised."
Scherzinger reportedly wants Tinie Tempah to join her for the Judges' Houses stage of this year's X Factor.
She previously confessed that she won't wear her heart on her sleeve as much when she returns to the show.
The X Factor's ninth series starts on August 18. Watch a trailer below:
