The 50-year-old Scottish singing sensation – who shot to fame after appearing on 'Britain's Got Talent' in 2009 – is known for her fiery outbursts but has learned to control her emotions now she is older and more used to fame.
She said: "I'm ashamed to admit it, but yes. But I'm getting a wee bit older now and I'm more used to it. You get nothing done by shouting and bawling. I'm not proud of it but I was known as the Miss Piggy of temper."
The 'Wild Horses' hitmaker – who famously declared she had "never been kissed" when auditioning for 'Britain's Got Talent' also admitted she is "lonely" and wants to find a "special" man who can "calm" her down.
