London: Singer Cheryl Cole and her boyfriend Derek Hough are set to seal their romance with a tattoo of a pair of lovebirds.
The pair have had sketches drawn of two birds to symbolise soul mates and best friends, reports dailystar.co.uk.
Earlier this week Cheryl, 27, and Derek, 25, went to a tattoo parlour to discuss about some designs.
"Cheryl and Derek have become so close that they wanted to mark their friendship," said a source.
"Cheryl credits Derek with saving her life as she battled malaria and they will always be close because of that," he added.
