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

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.
