Cheryl has been branded a “sperm bandit” by campaign group Fathers4Justice.
The 36-year-old singer - who has a two-year-old son Bear with ex Liam Payne - recently revealed she would like to have two more children and is seeking sperm donors from abroad.
Matt O’Connor, founder of fathers’ rights organisation Fathers4Justice tweeted: “Sperm bandit Cheryl doesn’t give a toss about dads. She wants to deny two kids their human RIGHTS to a dad.”
The Fight For This Love singer welcomed her son Bear in March 2017. She split from his father, former One Direction star Payne, 26, in July 2018 and they co-parent Bear.
Cheryl, who is currently single, told The Times Magazine, she is seeking fertility treatment as she would like to have more syblings for her son.
She said: “If time was on my side and I was in my twenties, yeah, I would wait and consider more options, or wait for somebody I felt was right, but…”
Cheryl, who is curretly starring as judge on BBC show The Greatest Dancer, confirmed that she wants to have a second and third child using a sperm donor from “out of town”.
She explained: “You can get it from abroad.”
Fathers4Justice have a history of publicly attacking celebrity mothers.
Following the death of Kerry Katona’s estranged husband George Kay last year Matt O’Connor tweeted that she had “blood on her hands”. The pair were parents to five-year-old daughter Dylan-Jorge but Kay - who had battled drug addiction - had lost shared custody.
