"We are so smitten." Nikki Phillips has given birth to a baby boy.

Nikki Phillips has announced the arrival of her first child, a “handsome little man” born Monday morning.

“Baby Phillips Rumble. Born 17.07.17 at 8.47am weighing 3.5kg and height 53.5cm (yup has my legs),” the New Zealand-born model, TV presenter and blogger wrote on Instagram.

“We are so smitten and all doing well.”

The journey to parenthood has not been an easy one for Phillips and her jewellery designer husband, Dane Rumble.

The 33-year-old, who was treated for Stage Three cervical cancer in 2009, revealed earlier this year that, like so many women, she had experienced the tragedy of pregnancy loss.

"After two years of trying and three miscarriages, I thought it was never meant to happen for us and also couldn’t help think, ‘What is wrong with me?’" she wrote on Instagram. "It was the most emotional roller-coaster I have ever been on, from extreme highs to devastating lows."

Our handsome little man is here... #BabyPhillipsRumble. Born 17.07.17 at 8.47am weighing 3.5kg and height 53.5cm (yup has my legs) We are so smitten and all doing well. Thank you to my amazing insta fam for all your loving messages. We feel extremely blessed and our hearts are exploding. No name yet, just taking it all in! ❤️ @danerumble #babyboy #birthdayboy

But today, the biggest high of all.

"We feel extremely blessed and our hearts are exploding," Phillips wrote Monday alongside the beautiful photograph of her little boy's feet.

As for a name, the couple previously told The Daily Telegraph they've got a few in mind, but wanted to "meet him before we decide".

But for now at least, Phillips says, the decision can wait.

"Just taking it all in!"
