The former frontman of Lostprophets has allegedly been grooming a woman behind bars as he serves a 35-year sentence for planning to rape a baby.
The Daily Mail reports Ian Watkins, 40, is said to have been writing to a 21-year-old single mother, who first met him as a fan when she was just 16, from his cell at Wakefield Prison.
But when she came to visit the disgraced star in jail, he made a joke about her two-year-old daughter seeing her have sex, it is claimed.
The Rooftops singer was jailed in 2013 for a number of child sex crimes.
The Sun on Sunday reported the mother, who has not been named, has now had her child taken into care after social services were alerted of her contact with Watkins.
