Cheryl Cole is currently rehearsing for her upcoming tour

Cheryl Cole's mum Joan Callaghan is said to be worried about her daughter's relationship with new man Tre Holloway.

Cheryl, 29, has been dating the American dancer for several months but her protective mum, who met Tre at a party last month, is wary of him.

It's early days and she isn't 100 per cent sure of Tre yet,' claims a source.

He looks good on Cheryl's arm but Joan fears he will not be there for her long term.'

Joan, 53, has always been close to Chezza and even lived with her when she was married to footballer Ashley Cole.

After that relationship ended in divorce in 2010, the concerned mum is understandably protective of Cheryl.

Any man dating Cheryl should be aware they have to pass the vigorous test and standards set by Joan,' the source tells The Sun.

She sees herself as more of a protecting force than ever. As it stands Tre has a long way to go before he is accepted.'
