“He's just a little ray of sunshine and his brothers just adore him,” she tells PEOPLE. “And when you're having a new baby coming into the home, you often wonder, you're like, ‘Oh, how are the boys going to react?’ But they adore him.”

Kerr shared that the connection between her youngest son and one of his siblings was strong before he even arrived, as she recalled one sweet moment she had while pregnant involving her son Myles.

“Ever since I was pregnant with Pierre, [Myles] would kiss my stomach every day and now he continues to kiss and hug his brother every day because that's how much he adores being a big brother,” she tells PEOPLE.

“I feel so blessed to have him,” she told the outlet.

The fashion veteran also spoke about having the desire to become a mother from an early age. “Growing up, I was a bit of a tomboy. I would often watch my dad fix V8 car engines and fit hotdogs [mufflers] on to exhausts, but I always knew I wanted to be a mother,” said Kerr.
