Cheryl Cole and ex-husband Ashley are "properly dating again" after spending the weekend together.

The former 'x factor' star celebrated her 28th birthday in London on Friday (01.07.11) and the soccer player was among the guests, while the pair reunited again for drinks on Saturday night (02.07.11) and at a friend's barbecue on Sunday (03.07.11).

A family friend told The Sun newspaper: "It's done and dusted. They spent the entire weekend together and properly dating.

"They were out on Saturday night for drinks, but decided against a late night and went back to Cheryl's early.

"Ashley loves his barbecues and they met up at a mutual friend's on Sunday. They have drawn a line under everything and they are starting afresh."

Cheryl has decided to give Ashley, 30, another chance but before she fully commits to him she has asked the sportsman to prove he has changed.

The pair - who divorced in 2010 following revelations the Chelsea and England player had cheated on her with a string of women during their marriage - have even reportedly discussed starting a family together.

A source told the Daily Mirror newspaper: "He makes her happy and that's the bottom line. The main reason they got back together was because they both realised they wanted to start a family and they could not live without one another.

"The first time around Cheryl's career came first, but this time family is her priority. They both want children.

"His brother Matthew was about to have his second child and Ashley wants kids of his own. He realised no one else came close to Cheryl, no one else made him feel secure and loved. Cheryl felt the same."
