Liam Payne and Naomi Campbell are said to be having a 'mind-blowing' time together after they were first pictured on an evening out earlier this week.

The rumoured couple, with a 23-year age gap, were first spotted with each other at the O2, in London but they partied in the New Year together, in Ghana.

It is claimed Cheryl's ex is 'smitten' with Naomi after sparks reportedly started flying between the pair two months ago, according to The Sun.

A source told the newspaper: 'Liam has been seeing Naomi for a while. He's mad on her. He seems head over heels.

'They are definitely an item and have been seeing a lot of each other. Liam thinks she's amazing and beautiful and has said their time together has been mind-blowing.

'He seems really into her and acting like he can't believe his luck... He obviously likes a beautiful older woman.'

MailOnline has approached representatives for Liam Payne and Naomi Campbell.

Speculation about a romance has been rife ever since Liam and Naomi appeared to flirt on each other's public Instagram accounts.

The supermodel showed off her new cropped hairdo in a sultry snap on social media, shared with 6.4million followers.

Among her greatest admirers, Liam didn't mince his words as he told the model she was 'perfection' and he playfully teased 'don't give me those eyes'.
