JLS star Aston Merrygold believes The Saturdays are the "biggest" girl group in the UK.

The singer made the claim in an interview with Capital FM, choosing the 'What About Us' ladies over the likes of Girls Aloud and Little Mix.

The bold statement comes as The Saturdays try to break America with their US reality TV series Chasing The Saturdays.

Merrygold added that the rest of the world is finally getting to see the group in action, saying:

"They are so talented. They are, in my eyes, the biggest girl band in this country and obviously – in the States and around the world – they're finally getting to see that as well."

He continued: "All of the girls are so lovely and we love them to bits and we're so so pleased for them."
