Although she's generally quiet about her private life in the media, Cheryl Fernandez-Versini knows when to speak up and set the record straight.
And that's what she seems to be doing this week, after some fairly serious allegations of drug use.
The singer was pictured in a public toilet at last Sunday night's British Fashion Awards, washing her hands next to what appeared to be four white lines of powder.
Although the photo was deleted just minutes after it was posted by fashion editor Laura Craik, the image was screen-grabbed and posted online.
And now, almost a week on, Cheryl has taken to Instagram to show she won't be taking any false accusations lying down.
"On the phone to my lawyer like," she wrote next to a picture of a sassy-faced Barack Obama speaking on a mobile phone.
"#Tryme #oohwatchmewatchme #allofthelightsallofthelightssss," she added.
Posting earlier in the day, the X Factor judge seemed determined to stay optimistic despite her rough week. "Positive vibes," she wrote, next to a quote about holding on to "genuine people."
Cheryl has spoken up in the past about negative comments online – mainly about her noticeable weight loss over the last year.
"I am so sick and tired of it being ok to call somebody too thin or a ‘bag of bones’," she wrote on Twitter earlier this year.
"I would never dream of calling somebody too fat and that they should maybe cut down on their food intake? What is the difference?"
