Meanwhile, Liam, 24, also followed suit yesterday by announcing their split via social media.
Posting a near identical message to his baby mama, he said: The news comes after Liam failed to publicly wish Cheryl a happy birthday yesterday.
Rumours that Cheryl and Liam are eager to start a family together have been circulating for a while - and after managing to keep a low profile and a social media near-silence for the past few months, fans were convinced that these snaps of Cheryl and Liam's first public appearance together for months appeared to show her sporting quite a large baby bump before Christmas.
Following all the talk about when they couple will announce the pregnancy, Liam's sister spoke out on Twitter and told people that it's really up to the her brother and Cheryl as to what part of their private lives they share with the public... That’s what I’m going to call my first child if I had children" - we wonder what Cheryl makes of that name then?
It's like it's the only thing in the world that matters to her. Cheryl has a stash of pregnancy and motherhood books she's always reading." It's definitely been one of the fastest-moving relationships ever - less than a year after getting together, the couple moved in together and apparently talked about having a family.
They previously shared an image of their 'new family member' on Cheryl's Instagram, but the baby talk was a whole new level.
Fans reacted to the pair's split on social media, with one commenting she was "so sad" to hear about the break-up.
I'm completely in awe of his incredible mother and how she has been the whole way through this, she's really made my dreams come true. " I am proud to announce that I am one of fifteen ambassadors working with @Princes Trust & LOreal Paris UK to help thousands of young people turn self-doubt into self-worth.
Cheryl shared a rare selfie to mark turning 35-years-old, but Liam was nowhere to be seen.
She instead spent her birthday with fellow Girls Aloud bandmates Nicola Roberts, 32, and Kimberley Walsh, 36.
Before he began dating Cheryl, the One Direction singer was asked in an interview about what he'd like to name his first child and his answer was Taylor. Fans previously commented that Cheryl had a hint of a bump visible in her jumpsuit back in May, as she'd been looking a lot healthier than her worryingly slender days during the end of her relationship with former husband Jean Bernard Fernandez-Versini.
Cheryl's PR team shared this picture of the singer on their Twitter...
