Boxing legend Jeff Fenech's daughter announces she's pregnant with footy star Bradman Best's baby

Jeff Fenech's daughter Kayla has revealed she and NRL star Bradman Best are due to have a baby in January next year, telling her social media followers, 'We can't wait.'

The 29-year-old started dating the Newcastle Knights star early last year - initially angering her boxing legend dad - and the big news got a heartfelt reception from her family and NRL identities.

'Omg I'm so proud of you both, can't wait to meet my gorgeous little bubba,' Kayla's mother Suzee wrote.

'Super excited to be on this next chapter/journey with you both. Luv u both.'

Best's Knights teammate James Schiller commented, 'Prodigy in the making! Congrats fam,' and the couple also got messages from former NRL stars Cooper and Jack Johns, as well as NRLW premiership winner Millie Boyle.

Kayla - who was holding an ultrasound image of the baby and a tiny pair of Nike shoes in one of the photos in her post - previously revealed her dad's furious reaction when he first learned about her romance, saying he went 'apes**t'.

However, the four-weight world champion soon changed his mind.

'I'd always warned my girls about going out with league players,' he said.

'I've been knocking around with footballers all my life.

'They're young and they love going out and having a good time.

'So when she rang and told me, I went off the deep end. I gave her a roasting. She kept trying to say, "Dad, he's a lovely guy". Kayla was telling me every day how nice he was.

'Bradman knew I was angry, but he told Kayla, "I'll prove your dad wrong" - and he has.'

The country's greatest ever fighter and Best now get along well, with the pair even doing some boxing training together.

'Maybe he was trying to impress his future father-in-law,' Jeff said.

'He was very impressive when we trained.

'When we first met, you could tell he was a good young man. He's treating Kayla beautifully. Like a gentleman. They're very happy. And so is my wife Suzee and I.

'The only time I got dirty is when he scored two tries against my Parramatta side last weekend and beat us.'

Kayla, who met Best through social media, moved to Newcastle to be with him.  

'He's a good person, very down to earth, and treats me really well,' she said. 

'Just an all-round good person with a big heart.

'He's actually perfect.'

In February, Kayla revealed one of the secrets to making their relationship work: she won't let him do any work around the house.

'To be honest, Bradman always tries to help. I don't let him,' she said.

'I learnt from my mum [Jeff's wife Suzee] that it's kind of a woman's job to keep the house intact.

'But he always tries to help me do the dishes but I don't really let him lift a finger in the house because I don't feel like it's his job to do that.

'He is always so busy with footy and when he gets home, he is tired so I would never expect him to do anything.'
