The images have prompted criticism from British anti-drug charity Re-Sol, who have labelled the 28-year-old singer as "irresponsible".
Speaking to The Sun on Sunday, a spokesperson for the singer insisted that she in no way meant to act irresponsible and would not have shared the images if she knew if would have a negative impact on fans.
"If Mutya thought her actions would have a negative impact on her fans in any way she wouldn't have put the pictures up," the spokesperson said.
Mutya is currently promoting her new single Flatline with band MKS - originally known as The Sugababes. On Saturday she took to the stage to perform with band members Keisha and Siobhan at the LGBT Hove Pride event.
