Liam Payne and Cheryl Tweedy have announced they are to split up after two years, as they say their baby son, Bear, remains their "world".

The singers made their "tough decision" to part two weeks ago, with reports that the break-up is amicable with "no third parties involved".

The former Girls Aloud star, 35, and One Direction member, 24, have a one-year-old son, Bear.

The singers announced they were "going our separate ways" in nearly-identical posts to their 40 million Twitter followers.

Describing how they "still have so much love for each other as a family", they added: "Bear is our world and we ask that you respect his privacy as we navigate our way through this together."
