Posting a picture which read: "Girls compete with each other, Women empower one another," the X Factor star wrote: "It can be so hard at times being a girl, for sooo many reasons! But we don't have to make it harder for each other.. Why do we still feel the need to do that ?? I don't understand it."
It comes after another drama-filled week for 'Chiam', who enjoyed a very public date this week in London.
Joined by Cheryl's mum Joan, the duo hit Salmontini le Resto on Wednesday evening in matching black outfits and looked smitten as they left hand-in-hand.
The 1D singer star shared an old photo of the X Factor judge on Instagram, alongside a romantic message - admitting: "Hope I make you as happy as u make me."
The photo, taken a while ago, shows Cheryl smiling at the camera in a natural shot, wrapped up in a thick red jumper.
Liam wrote: "Happy#internationalwomensday to my favourite woman in the world hope I make you as happy as u make me X."
It must be love.
