Celeb pals Jackie O Henderson and Sophie Monk are a perfect endorsement of that statement, having enjoyed a close bond for over 20 years.
And proving the duo are closer than ever, Love Island Australia host Sophie was spotted leaving a luxury birthday gift for her best friend at Jackie’s work, KIIS Studios, in Sydney on Monday.
The 39-year-old TV host looked typically stylish in a blue halterneck dress featuring vertical stripes and a floral pattern.
She accessorised the summer frock with a royal blue cross body bag and a pair of sky high tan wedges.
Pinning her hair in a messy up do with a centre parting, the socialite cut a stunning figure as she stopped by the radio network clutching a disposable coffee cup.
The former Bachelorette carried a dainty black bag from fine jeweller Luke Rose, which reportedly contained a $500 gold bracelet for her BFF.
Speaking on the Kyle and Jackie O show, Sophie referenced the gift and revealed she chose it out of jealousy over Jackie's growing camaraderie with Sydney PR maven Roxy Jacenko.
After feeling left out when Jackie and Roxy went on a sun-soaked holiday together in late December, Sophie said: "I saw her with Roxy and I got so jealous. That's half the reason I bought you a friendship bracelet because she hasn't got one, has she?"
