British pop star Nicola Roberts has undergone a teeth-straightening procedure to fix her crooked smile.
The Girls Aloud star admits she has always longed for perfect teeth, and recently plucked up enough courage to go through with the dental procedure.
She tells Britain's Radio 1, "I wanted it done for ages."
Her Girls Aloud bandmate Sarah Harding recently admitted she underwent a lip-plumping procedure and hated the results, so Roberts is adamant she won't be trying any more invasive cosmetic treatments.
She adds, "Don't get me wrong, I do indulge in lip plumper gloss. But where do you stop? You have to do what makes you happy."
