The 29-year-old 'Call My Name' singer and her backing dancer lover are getting serious about each other, and the American is looking at apartments in London to support Cheryl on her tour in October, reported Daily Mirror online.
"After a tough couple of years, Cheryl has most definitely got the spark back in her eye. She is really, really happy - and can't stop grinning," a source said.
"Tre is working with her on her solo tour and will support her for the Girls Aloud reunion so he'll be in the UK for the foreseeable future; it makes sense for him to start house-hunting," it added.
Tre is the first man Cheryl has gone public with since splitting from her husband Ashley Cole in 2010, although she had been romantically linked to ballroom dancer Derek Hough and close friend and manager will.I.Am in the past.
