Una Healy and Rochelle Wiseman both became engaged in 2011

The Saturdays' engaged singers Una Healy and Rochelle Wiseman are planning a joint hen do.

Una, 30, and Rochelle, 23, both said yes last year and will party with a group of friends - likely to include band mates Frankie Sandford, Mollie King and Vanessa White - before they become married women.

'Rochelle and I are probably going to do something together,' says Una.

Both Rochelle's fiancé Marvin Humes and Una's future husband Ben Foden have already had their stag dos.

Rugby player Ben, 26, got into a bit of trouble after his night out in Barcelona when photos emerged of him pole dancing naked in a strip club.

While Una has forgiven her partner, it's unlikely that her bash will be quite so wild.

'I don't drink a lot of Guinness,' Una tells The People.

'Maybe a glass but I don't think I'd be able to take on a pint.'
