Cheryl has been pictured with a very noticeable bump, adding to speculation she and boyfriend Liam Payne are expecting a baby.ch
Rumours have circulated for months and picked up steam again after the 33-year-old was pictured in a figure-hugging green jumper-dress on newspaper front pages.
She was at a charity Christmas concert in London with One Direction star Payne, 23.
A spokesman for the former X Factor judge said she would not be commenting on the rumours.
The celebrity couple have been together since last December and Cheryl's divorce from restaurateur Jean-Bernard Versini was finalised last month.
The pair were married for 19 months after tying the knot after just three months.
Famously part of hit group Girls Aloud, Cheryl became the first British woman to have five solo number ones when her song I Don't Care hit the top spot in November 2014.
The singer has also set up her own charity, Cheryl's Trust, that works with The Prince's Trust to help disadvantaged young people.
