London: Cheryl Cole`s mother Joan Callaghan is reportedly embarrassed by her daughter`s full rose tattoo on her back.
Callaghan is said to have warned her daughter about the tattoo and feels it may not be as appealing when the pop star grows old, reported Contactmusic.
"Joan called Cheryl and told her you`ll regret that when you`re older," a source said.
The `Call My Name` hitmaker got the far-reaching tattoo, which extends from her lower back to her posterior, in February but had only shown off the upper half.
The full extent of the body art only came to light last month when tattooist Nikko Hurtado posted a picture of it on photo-sharing website Instagram.
