Perrie Edwards has been flashing her very toned stomach.

The Little Mix star teamed a sports bra with tight black leggings to film a new clip for the girls’ Instagram page with Jesy Nelson, 22.

‘Little Mix strong girl competition down on the set of the @sportrelief #WordUp video shoot yesterday,’ they posted.

‘Jesy vs. Perrie…Who’s gonna be victorious?! xx Little Mix xx.’

Zayn Malik‘s fiancée, 21, isn’t the only member of the band to have flaunted her trim tum in recent days.

Jade Thirlwall, 21, and Leigh-Anne Pinnock, 22, displayed their six-packs yesterday as they made up a racy dance with Jesy. 

‘Sexy time slow jamz,’ the trio joked alongside the funny footage.
