Mark Owen and his wife Emma Ferguson have reunited and are reportedly trying for a third child.
The Take That singer - who earlier this year confessed to having a number of affairs since he began dating Emma in 2004 - has returned to his spouse after spending a month in rehab to deal with his alcohol problems.
The pop star has agreed to go for marriage counselling sessions and has suggested they try for a third child.
A source said: "Mark is itching to resume family life. He has not touched alcohol in five weeks and has done a lot of naval-gazing as well as receiving serious professional counsel.
"Emma knows he is a great dad. She has agreed to give their marriage one more try on the proviso he behaves himself, doesn't so much as look at another woman and attends marriage counselling. Mark has agreed to all her terms. And he has even suggested they try for another baby to cement their relationship."
The couple - who have 16-month old daughter Willow Rose and son Elwood, three, together - have been dating since 2004 and wed six months ago in Scotland, in a star-studded ceremony attended by his bandmates Gary Barlow, Jason Orange and Howard Donald.
Since the 38-year-old star revealed his alcohol problems and multiple infidelities, Mark has been supported by his bandmates, in particular Gary.
The source added to the Daily Mirror newspaper: "Another influence was Gary Barlow who has been a rock for both Emma and Mark. He's been telling Mark to pull his socks up. It was the talk he needed."
Mark is expected to return to his marital home in Wandsworth, south London, in five days.
