Cher 'grateful' for Cheryl's help

Cher Lloyd feels like she "owes" Cheryl Cole.

The 'Want U Back' hitmaker - who was mentored by the Girls Aloud singer on the 2010 series of 'The X Factor' - admits she put her "foot in it" when she accused the 'Parachute' singer of miming and relying on computer auto-tuning to perfect her vocals, but she is "very grateful" for all Cheryl's help.
