While officially neither have spoken out about the rumours in the press over the past few months, new pictures basically confirm it.
Either Cheryl's been smuggling jumpers up her top or she and Liam are totally expecting a little one.
New snaps from an event today show Cheryl arriving with Liam and showcasing a very noticeable bump.
And for once, she wasn't even trying to hide it.
The pair’s romance surprised us all when news of it first broke back in February of this year.
Rumour has it that the pair got together back in December 2015 after meeting up backstage at The X Factor final.
They’ve since constantly shared adorable loved up snaps on social media and recently X Factor boss Simon Cowell spoke out about the loved up couple.
“I saw them together and we had a really nice dinner,” he revealed. “They were on good form.
“They’re like two little chipmunks madly in love. Literally, they were so cute.”
Simon said he had ‘no clue’ about Cheryl and Liam’s relationship until it hit the front pages of the tabloids.
“I’m not going to talk about the past,” Simon added to The Sun newspaper, “But importantly they both seemed very happy over here and very relaxed.
“I’m happy for them.”
Cheryl, who was a judge on The X Factor when Liam first auditioned back in 2010, left the show this year, saying at the time: "I've missed making music. I have had such an amazing experience being a judge on The X Factor.
"I have learnt so much and enjoyed nurturing talent but I've missed making music and am excited to be recording again."
We say congratulations and best of luck to them!
