The Saturdays ''sex up'' their dance routines when their partners attend shows.

Mollie King has revealed her loved-up bandmates - including Rochelle Humes, Frankie Sandford, Una Foden and Vanessa White - will be going all out to impress their boyfriends and husbands when they embark on their greatest hits tour in September.

She said: ''It's funny when everyone's husbands and boyfriends are in, everyone tries to sex it up. So if Wayne [Bridge, Frankie's soccer star fiance] comes down I'll look over at Frankie and she's giving it extra large and I'm like, 'I saw you.' ''

The 'What About Us' hitmakers will also be travelling with a full entourage as Frankie and Rochelle will bring their children on tour with them.

Rochelle, who has 12-month-old daughter Alaia-Mai with husband Marvin Humes, said: ''There will be a lot of juggling. I'm not being without Alaia-Mai.''

However, Una will leave her two-year-old daughter Aoife Belle - whom she has with rugby player husband Ben Foden - at home as she is due to start pre-school.

The red-haired star told Britain's OK magazine: ''Aoife will be starting nursery so I'll pop back to see her.''
