The Saturdays - Mollie King Backing British Heart Charity's Campaign
The pop star is supporting the British Heart Foundation's National Heart Month, which takes place in February (13), in honour of her grandfather, who died after suffering a heart attack.
King is calling on her fans to back the charity's Rock Up In Red campaign, which involves Brits donating $3.20 (£2) to wear a red item of clothing to raise awareness of the cause on 1 February (13).
She says, "I'm thrilled to be supporting the British Heart Foundation this February by Rocking Up In Red and joining the fight against heart disease. It's a cause very close to my heart, as my grandfather sadly passed away after suffering a heart attack when I was younger."
