Cheryl fuels Liam Payne dating rumours with 'mystery man line-up'

Cheryl Fernandez-Versini has fuelled reports she is dating One Direction star Liam Payne by posting a 'mystery man line-up' on her Instagram page.

The former Girls Aloud star posted a snap of Liam along with two other men with the hashtag #whoisit #whosworthit.

Hours earlier she posted a picture of herself with a man's arm around her shoulders, prompting many fans to speculate it was Liam.

Cheryl's posts come days after Liam changed his Instagram profile picture to one of them together, which appeared to show him bare-chested.

He later deleted it and updated his status to 'happy'.

But today he posted another snap of them travelling in a car with Cheryl giving the peace sign.

Cheryl is currently going through a divorce from her second husband Jean-Bernard Fernandez-Versini, 35.

She was previously married to footballer Ashley Cole, who she divorced in 2010, following allegations he cheated.

While Liam, who is currently on a break from One Direction, split with his girlfriend of two years Sophia Smith in October.
