Cheryl and Liam Payne have kept the public on their toes since they first revealed they were dating on Instagram.
They have since made several public appearances, posted cute photos together, bought a dog together and have left everyone wondering whether they're expecting their 'first child' together.
Cheryl and Liam have neither confirmed nor denied the pregnancy rumours but after the pair stepped out at the Fayre of St James Christmas Carol Concert in London people noticed a 'baby bump'.
And after everyone had congratulated the couple, Liam's older sister Ruth hit back at the pregnancy speculations by tweeting: "Bump or no bump, announced or not, it's completely up to my brother and Cheryl what parts of their private lives they choose to share and when."
Even though Liam has only recently made a huge public gesture by following Cheryl on Instagram, it has been reported that the singer will propose to Chezza after she gives birth.
The 23-year-old has apparently taken inspiration from when Justin Scott proposed to Kimberly Walsh, Cheryl's ex-band member, shortly after she had given birth to their son Bobby in 2014.
Kimberly explained the story to Hello! magazine: "I'd just handed Bobby to Justin, so he had our gorgeous new-born son in one arm and I remember Bobby had his eyes open.
"Bobby didn't take his gaze off me as Justin slipped his other hand into his pocket and suddenly the pair of them were sinking down towards the floor.
"I said, 'What are you doing?', then Justin pulled out this gorgeous ring."
How adorable!
And now according to the Daily Star a friend of Liam and Cheryl's has revealed that Liam got his proposal idea from Justin: "It's given Liam so many ideas.
"There will definitely be wedding bells sooner than we expected."
Eek!
We reckon if the pair do have a wedding it'll be VERY private.
And Liam's friend and boyband member Niall Horan has been spotted with leaving the baby boutique Petit Tresor in West Hollywood this week with a basket of pink items for a baby girl. Whether they're for friends or family is unknown…
