'Pregnant' Cheryl has kept her stomach hidden in a new picture from Kimberley Walsh's birthday bash.

She has been at the centre of the pregnancy rumour for long time. With growing speculation about her pregnancy, she kept her tummy hidden under a baggy jumper as she sat around the table with a group of friends.

Kimberley shared a picture on Instagram and captioned it, ""Lovely birthday meal thanks to @love_entertainment_ and @chakraevents. Nothing better than good food, good friends in the comfort of your own home! #pregnant."

Alongside, Cheryl took the social media to wish her best friend a happy birthday, "Another birthday for @kimberleywalshofficial and another amazing year to have shared with you."

"From getting married to having another bambino on the way. Happy birthday babe. Can't wait to see who and what the next year brings for you.

"Love you more with each passing year Kimba."

It is believed that the pair (Liam Payne and Cheryl) started seeing each other on the X Factor set where they were introduced by none other Simon Cowell.

Cheryl's divorce from French restaurant entrepreneur Jean-Bernard Fernandez-Versini finally completed last month.

Cheryl and Liam have kept their relationship as low profile as possible, before finally confirming it in February. They were spotted together in a supermarket in Guildford, Surrey.

Shortly before the birthday bash, Cheryl gushed about the happy state of her life to Fabulous magazine. She also revealed that she is learnt to be comfortable in her own skin: "I am happier than I've ever been before. Now is a very good time in my life."
