Casey and Jack enjoyed a whirlwind romance just nine months after his split from former Love Island co-star Dani Dyer and split before Blossom was born.
Jack chose to keep news about their unborn child private while he "prepared for the new responsibility".
But now Casey, who works in the NHS, has spoken out about her relationship with Jack, posting a quote on Instagram that read ‘The job of two is done by one, the job of two is done by mum.’

Maura Higgins - Series 5
Irish babe Maura Higgins is one of our all-time favourite Islanders and number one bombshell of all time. Maura entered the villa on Day 10 and went on to leave in fourth place alongside ex Curtis Pritchard. Maura has since proven to be Love Island gold, she went on to take part in Dancing On Ice in early 2020, released a collab with Ego shoes, and landed a HUGE deal with lingerie brand Ann Summers.
Admitting in the long caption that she was hesitant to open up, Casey revealed that she has given Jack multiple chances to build a relationship with Blossom.
The lengthy post read, "As I write this post with an open heart I can’t help but feel a lot of anxiety & discomfort surrounding my choice to speak up on such a private matter. Having a part of my life played out so publicly is beyond difficult to deal with - I keep my personal life private & I never acknowledge any rumours/speculation surrounding private matters.
"However, it’s been testing at times & there have been a couple of occasions where I’ve had no choice but to address the lies being told that have involved my daughter. Before posting this, I have spoken with my solicitor so I’m fully aware of what can and can’t be said. Due to legal reasons, I’m very restricted."
She continued, "My intention right now is to set the record straight due to the truth of this matter being twisted & manipulated to fit those who are living a lie. The truth is, I have given Blossoms biological father repeated chances to build a relationship with her, I have dismissed his deceitful & conniving behaviour and I have forgiven things that should never have been forgiven - but I did, for the sake of my daughter & him being a part of her life.
"Sadly, he has let her down each time & proved on MANY occasions that he isn’t worthy of being a 'father'."

Casey continued, "Due to his own behaviour, choices & actions - he has no relationship with Blossom & hasn’t seen her since the start of April. Previous to that, he hadn’t seen her since June 2020 (again, this was down to his own actions) his reality is a reflection of his own choices and I will not be blamed & labelled as the 'bitter mother' because that’s the easiest & most convenient card for this 'victim' (& his family) to play.
"The fact is, these people are so in denial of the truth & think it’s acceptable to spread lies & malicious gossip about me surrounding the reasons as to why they have NO relationship with my daughter.
"I am not to blame - if anything, I tried with my whole heart to support a relationship between Blossom - him & his family and I’ve made peace with the fact I did everything I could.
"Sending love, light & healing to those with ill intentions & bad vibes ♥️"
Casey’s post comes after Jack’s split from TOWIE star Frankie Sims and a recent brush with the law after he was arrested on suspicion of driving under the influence of drugs.
He was later charged with two counts of drug driving offences – which he pleaded not guilty to.
