The former ‘X Factor’ judge and One Direction star looked smitten with each other as they posed for pictures together on Monday night, confirming their relationship.
They were attending former ‘Desperate Housewives’ star Eva Longoria’s Global Gift Gala at the Four Seasons Hotel in Paris, and couldn’t keep their hands off each other.
Cheryl looked stunning in a powder pink, floor-length gown with cut-out details on the waist, by the Olsen twins' label Elizabeth and James.
The former Girls Aloud star was there to accept the Philanthropist award for her charity Cheryl's Trust.
She said: "It's an honour to be here. I'm thrilled to be getting an award for the charity."
The singers haven’t been out of each other’s pockets since getting together last December, spending time together in Los Angeles, London and during a Maldives mini-break.
They are also set to put in an appearance at this year’s Cannes Film Festival, where Cheryl's estranged second husband Jean Bernard Fernandez-Versini will also be in attendance.
She split from the French businessman last year after 19 months of marriage.
Last month Cheryl hit back at Jean-Bernard's claims that she had begun her relationship with Liam while they were still together.
Writing on Twitter, she insisted: “If anybody believes the shit they’re reading today you really don’t know me at all.”
Similarly, a spokesperson for Cheryl told MailOnline: “Cheryl does not and is not going to comment upon private matters. Jean-Bernard’s information about when Cheryl started her relationship with Liam is false.”
