The RTÉ presenter lost her sister to cancer when she was only 33 years old.

Miriam shared a photo of her and her late sister with their babies on Instagram to mark her anniversary.

"Today is my adored sister Anne’s anniversary - she died aged 33 from cancer. Hard to believe it’s 30 yrs," Miriam wrote.

"This is my favourite photo of us both, wrecked new mums holding our baby daughters," she continued.

Miriam said their daughters have remained incredibly close following her sister's passing.

"The only happy part of all of this is that those two little cousins are now best friends," she wrote.
