Scherzinger, 33, who has an on-off relationship with the Formula 1 racer, said her filming dates clash with his sporting events, reported Contactmusic.
"I'm actually going to spend less time with Lewis. I believe the 'X Factor' shows are going to be running the same time as his races. But I'll juggle things. I think everything will work out the way it's supposed to. It'll be OK," she said.
Scherzinger, who judged her first full day of auditions in Newcastle upon Tyne, North East England on June 18, says her British boyfriend has been no help in preparing her for life in England.
"I think I'm still giving Lewis tips on surviving the Brits!"
