But The X Factor judge is reportedly planning to make a 'spiritual commitment ' to the dancer. The 27-year-old and Hough are rumoured to have been dating since she split from ex-husband Ashley earlier this year.
The couple have still not confirmed that they are an item, but a source told New magazine that they are set to have a symbolic ceremony next year.
A friend told the UK magazine, 'Derek wants to marry Cheryl next year at the latest. She's aware of that and felt she had to put him straight. She told him that she doesn't think she will ever marry again as she still feels betrayed by what Ashley did.
'But they will make some kind of spiritual commitment like a ceremony on the beach.'
