Nicole Priest, 23, who was jailed for 15 years for manslaughter last week, posted a TikTok video saying “I messed up bad” after killing her three-year-old daughter Kaylee-Jayde who was getting in the way of her sex life. Kylee was found dead with chest and abdominal injuries on August 9 last year. Priest’s boyfriend named Callum Redfern, 22, was also jailed for 14 years for manslaughter.

In one video, Priest mouths the words: “I’m sorry mum and dad. I know I messed up bad. I should’ve done, should’ve done better.”

In several other recordings, she posted tributes to her daughter before moving onto viral dances.

Priest was sentenced to 15 years with a three-year concurrent sentence for child cruelty, after Birmingham Crown Court heard that the mother only called 999 after her daughter was dead.

Mr Justice Foxton QC said: ”On the evening of August 8 you Redfern went to Priest’s flat.

“The two of you went to have sex. Kaylee wanted to stay up and play. There is no direct evidence of what happened next.

“Kaylee was sick more than once during the night as a result of the severe beating.

“You lost your tempers and it is clear you were joint participants in that assault. You both knew you had seriously injured Kaylee.”

He added: ”You, Priest did nothing to seek medical help. A prompt call could have saved Kaylee’s life. You both lied repeatedly during interviews.

He added that his son was misled by Priest and “got caught up in it”, describing him as a “kid” incapable of manipulating his ex-girlfriend.

The father also claimed that Priest reportedly refused to change Kaylee’s nappy, telling the three-year-old “you can just stay in it”, while she was smoking outside.

The court also saw CCTV footage that showed Priest with her daughter hours before the youngster’s death.

The footage shows Kaylee and her mother taking a lift together.

There is no interaction between the three-year-old and her mother at any point during the video.

Medical examinations of Kaylee, who was described as a “happy child”, showed recent chest and abdominal injuries, as well as historical injuries including broken ribs, lower leg fractures and a broken sternum, Birmingham Crown Court heard.

The court was also told that Priest would hit Kaylee and refer to her as a “f*g brat”.

Local residents claimed that Priest would try to silence Kaylee’s cries by playing loud music.

They also recalled a situation where Kaylee’s mother said she will justify the cries by claiming that “I’ll just say she fell off the bed”.

In a text message exchange a few days before Kaylee’s death, Priest told Redfern: “I’m gonna kill her… because she keeps leaving the living room or going in the kitchen, so I’ve paled (hit) her one and smacked her for s**tting in her nappy.”

Redfern said: “Good – give her one from me.”

Priest replied: “I will, babe.”

Prosecutors said the messages painted a vivid picture of the “uncaring attitude from Priest and Redfern towards Kaylee”.

Kaylee’s grandmother Debbie Windmill said the impact of her death would live with her for the rest of her life.

She said: “I could never stop staring at the smile on her beautiful face.

“I loved every moment watching her develop to nearly school age; preparing to buy my first grandchild her pre-school uniform was something that filled me with such happiness.

“I couldn’t wait to see her in it, but this opportunity was stolen from me in the most brutal of ways.

“Everybody deserves the gift of life. Kaylee-Jayde deserved to show the world who she could have been and what greatness she could have brought to this world. Nanny will forever hold you in her heart.”

Detective Inspector Adam Jobson, said: “This is a really horrific set of circumstances and I cannot imagine for one second what Kaylee-Jayde’s family must be going through, they’ve lost their three-year-old family member at the hands of her own mother and Nicky Priest’s boyfriend, Callum.

“It is a grim picture.

“I don’t think, sadly, we will ever fully know what has happened, we’ll never get that full picture, both have not admitted their own responsibility.”

He added: “One thing is clear, Nicky Priest has failed her daughter, she’s failed to protect her and she should be – being a mother to that little girl – the one person who should have been able to protect her.”
