Holloway had visited Cole's hometown in Newcastle a while back and now his mother Shirley wants to reciprocate by coming here, reported Sun online.
"Tre has already been to Newcastle to meet her mum and wanted to reciprocate. He can't wait for the three of them to take in the tourist sites," a source said.
The three also plan to visit Madame Tussauds's museum where there is a statue of Cole.
"There have been jokes about closing off Madame Tussauds for a visit to Cheryl's waxwork," the source said.
