It's getting serious...
The supermodel, 48, showed her appreciation for her rumoured beau’s good looks as she hit the ‘like’ button on a smouldering photo of Liam on Sunday.
In the image, Liam looks particularly dapper in a smart black suit as he poses on the red carpet at last week’s BRIT Awards at London’s O2 Arena.
He captioned the image: ‘Thanks for having me @brits. Congratulations to all the winners tonight!’
Naomi wasn’t the only one to give the photo a thumbs up as over 626,000 people also ‘liked’ the snap.
It’s not the first time the couple have flirted over Instagram either.
Liam previously commented on a selfie of Naomi, calling her ‘perfection’.
‘Perfection in a person… Don’t give me those eyes,’ he said, alongside a rose emoji and the blowing-a-kiss and eyes emojis.
She later returned the compliment by commenting on a shirtless snap of Liam: ‘Beautiful soul,’ alongside a heart emoji.
Meanwhile, Liam was left red-faced at the BRITs after host Jack Whitehall also ‘confirmed’ his relationship status with Naomi as he introduced him to present an award.
Unable to resist making a joke at Liam’s expense, Jack told the audience: ‘To present it is a supermodel and supermodel Naomi Campbell’s current squeeze.’
If that wasn’t uncomfortable enough, Jack, 30, added: ‘His surname’s Payne, which is what he’ll be in a world of if he crosses her.’
Liam and Naomi reportedly first got together in December and have been enjoying ‘mind-blowing sex’ ever since.
‘Liam thinks she’s amazing and beautiful, and has said their intimate time together has been mind-blowing,’ an insider told The Sun.
He seems really into her and acting like he can’t believe his luck… He obviously likes a beautiful older woman.’
