Rochelle Humes enjoyed lots of ‘mummy water’ at the weekend.

The Saturdays singer joined bandmate and fellow mum Una Healy, 31, for a few cheeky cocktails over lunch yesterday.

#mummywater #mexicanlunchhour @unathesats xx ,’ Rochelle, 24, captioned a photo of the pair on Instagram.

On Saturday night Rochelle, who’s mum to four-month-old daughter Alaia-Mai, also had some ‘mummy water’ with her own mother.

My Mumma staying over tonight, bottle of vino putting the world to rights ,’ Rochelle told her Twitter followers.

Shortly afterwards she admitted that she’d got a bit carried away, Tweeting: Getting picked up in 4 and a half hours and I’m still up with a glass of wine #mummywater‘.

It didn’t stop Rochelle from getting back to work though and she’s even threatened to take over her hubby Marvin‘s DJ slot on Capital FM.

@marvinhumes You’ve been sacked there’s a new girl in town @capitalofficial x,’ Rochelle wrote with a snap of her hitting the decks at the station.

Marvin, 28, didn’t seem too concerned though, Tweeting in response: hahahahaha x‘
