The musical couple were in attendance at the Fayre of St James Christmas Concert in London, which chose Cheryl's Trust as this year's official charity partner.
Cheryl, 33, and Liam, 23, were snapped leaving the festive event while being totally swarmed by photographers eager to catch a rare picture of them together in public.
The couple, who are thought to have begun dating towards the end of last year, have been at the centre of rumours they're expecting a child. Cheryl and Liam are notoriously private about their personal lives and have yet to comment on the rumours.
But what is clear is the fact they're totally smitten and blissfully happy.
A source tells the new issue of Reveal magazine: "Cheryl is absolutely loving life right now. She's been telling friend she's never felt sexier."
She certainly looks incredible, right?
As well as flashing a mega-watt smile for the cameras, Cheryl gave a speech at the event, which is billed as one of the most highly anticipated Christmas charity concerts of the year.
The event is held annually at St James Church in London, and features carol performances, festive readings and more. It is followed by the switching on of Jermyn Street's Christmas lights and an after party at exclusive restaurant Quaglino's.
Proceeds of this year's event will go to Cheryl's Trust, which Cheryl founded to help young people reach their dreams and live a happy life.
