Ouch! Caroline Flack, 39, was teased over her past relationship with Harry Styles, 25, as Keith Lemon mocked her for dating someone who was ‘too young to legally drink alcohol’
Keeping quiet: Caroline awkwardly shrugged as Keith quizzed her over the 2011 romance for his show, Shopping With Keith
He said: ‘It was well publicised when you went out with Harry Styles. Did you go out with him or was that just nonsense?’
But Caroline, despite having briefly touched upon the romance before, wasn’t having any of it and simply shrugged.
Keith responded: ‘Oh right then, that says enough things. Cos I remember when you were on Juice, I think you were worried I was gonna slate you for it.
Did you go bowling? Caroline dated the former X Factor star in 2011 when he was aged 17 and therefore too young to get served in a bar (pictured in November 2011)
‘But I said my biggest concern was bonfire night’s going to be really rubbish, because he’s not old enough to get sparklers, which was true.
‘Because he was at an age where he couldn’t have a drink, what did you do, just go bowling?’
Caroline shrugged once again.

‘Everyone’s starting to get, like, the same face on Instagram because of these Facetune things. I will admit, I’m going to admit it, I have used Facetune once.
Not giving anything away: Caroline kept shrugging her shoulders as Keith quizzed her further
‘You can alter the shape of your body, you can colour in your skin, or get rid of a spot, things like that.
‘And I used it once when I was on the beach and I had like a, fat back so I got rid of the…’
Keith chimed in: ‘You got rid of your back t**s.’
