The 26-year-old was recently spotted on a night out with the son of musician Paul Weller, and reports soon started gathering pace that they were dating.
However the star has hit out at the claims in her new column in UK's Closer magazine.
She said: 'I went out in London with my friend Natt Weller last week and woke up in the morning to stories that he's my new boyfriend.
'It's ridiculous - we've been friends for years. Just last week he was linked to Taylor Momsen. I suppose you have to laugh - who will he be 'linked' to next, I wonder!'
