Kris Boyson has revealed his new baby son’s name in a heartfelt Instagram video.

Katie Price’s ex announced the birth of his first child with fiancée Elizabeth Tierney on Thursday and has now shared that their little tot is called Bobby-Bleu Boyson.

The couple, who kept the pregnancy private, shared the news in an Instagram video featuring the newborn.

The clip showed their hands unveiling the baby, who was dressed in a personalised blue-and-white baby grow.

Well-wishes quickly followed, with Katie Price‘s ex-husband Kieran Hayler commenting: ‘Congratulations guys ‘ and TOWIE star Lauren Goodger adding: ‘Omg I didn’t even know you were pregnant! Gorgeous boy xxx’

Kris and Elizabeth began dating in 2022 and later got engaged. Despite speculation that they had split in 2023, they had secretly reunited and kept their relationship and pregnancy off social media.

Kris, 36,was previously in a high-profile relationship with Katie Price from 2018 to 2019.

This is Elizabeth’s second child, as she already has a young daughter named Arabella from a previous relationship who she has raised as a single mum.

Kris and Elizabeth, 33, were thought to have split, but the pair secretly got back together and couldn’t have looked happier as they were snapped out and about with the newborn.

Katie dated Kris on-and-off for just more than a year between 2018 and 2019, with her children reportedly referring to him as ‘dad’.

The personal trainer even proposed to Katie but it was not meant to be and the couple broke up in August 2019, with Katie admitting to Kris that she cheated on him.

Their engagement came while she was still legally married to her third husband Kieran Hayler.

Kris went on to date model Bianca Gascoigne, 35, following the end of his on/off romance with Katie before meeting Elizabeth Tierney.

Kris has previously boasted he will ‘fight all’ of Katie‘s exes after he nearly bumped into a few of them at a Christmas event last year.

He attended the Tulleys Christmas Light Festival in November where he narrowly avoided Katie’s other exes Carl Woods and Kieran Hayler.

In August, Kris recorded a TikTok video where he said he would ‘jump in the ring’ and box Katie’s current boyfriend JJ Slater after he was unhappy that she wrote about him in her book This Is Me.

Speaking to The Sun, Kris was asked if he still wanted to fight any of Katie’s exes and he said: I’d fight them all now. Are any of them here? I’d fight them all.’

‘There was a couple of situations, and listen I’ve always been as amicable and respectful as I can to all of my exes, but sometimes a few of them pipe up and say things they shouldn’t.

And sometimes their partners do the same, and unfortunately they’ll never say it to my face.’

MailOnline contacted representatives for Carl Woods and Kieran Hayler for comment at the time.

In her book, Katie wrote: ‘Then I was with Kris Boyson but he cheated on me and coming off the back of Kieran, I was devastated, so that damaged me too.’

Kris has denied these claims.

Meanwhile Katie is a proud mum to son Harvey, 22, with former footballer Dwight York, son Junior, 19, daughter Princess, 17, with her first husband Peter Andre, and son Jett, 10, and daughter Bunny, nine, with ex-husband Kieran Hayler.

Katie recently confessed that ‘men have always been the downfall‘ as she reflected on her wild love life in a candid new interview.

For years the glamour model, 46, has made headlines with her wild love life, including a string of ex-boyfriends and three high-profile marriages.

Speaking to The Sun, Katie reflected on some of her more unlikely conquests, including a passionate night she spent with Simon Cowell during her glamour model heyday, and swapping numbers with Hollywood star Jamie Foxx.

Referring to other men in her life, Katie said: ‘Men have been the downfall of me – my career has always been good and men have let me down.

‘I’ve picked the wrong men. They’ve been toxic or given me mental abuse, physical abuse, narcissistic behaviour, gaslighting, jealousy. I got used to that. I couldn’t spot a red flag.

‘Now I’ve had therapy, I can spot signs and realise what unhealthy relationships are. I feel good, I feel settled, I feel excited when I come home at night.’
