Having tamed her flame-coloured locks into a ponytail for the party, the singer rocked a tousled style as she let her curly locks down.

Nicola wiped away her heavy make-up from the evening before with a wipe seen on the shelf by the mirror.

As her friend was yet to leave bed in the background of the snap, Nicola joked in the caption: 'Good job she doesn’t have Instagram.'

Kimberley tried to wash away the hangover with a luxurious bubble bath at the resort as she slicked back her shoulder-length locks.

The singer admitted she was 'extremely hungover' and 'pretty sick' but said the bath was 'definitely helping' when she shared snaps with her fans.

Kimberley wrote: 'They don't have extremely hungover cow so this will have to do.'

The glamorous Saturday night celebrations ended with a performance from Gary Barlow - who even encouraged the birthday girl to sing alongside him. 

As they arrived, Rochelle treated her guests to monogrammed 'RH 30' grey pyjamas and a bottle of bubbly at the hotel and members club in Chipping Norton.

And throughout the busy weekend the mother-of-two got stuck in to a host of rural activities across the 400 acre venue.

The host showed off a legion of Tiffany blue bicycles with idyllic wicker baskets placed around the Soho Farmhouse which guests later used to get around.

Rochelle and Marvin even organised a breakfast van to cater to the guests on Saturday morning before they kicked off a football game on the hotel's grounds.

The singer captioned a snap of their antics 'boys will be boys' as they warmed up before one team came out top with an impressive 4 - 1 score.  

Later in the day, guests enjoyed a personalised cocktail menu, complete with RH 30 drinks stirrers before settling into a night of partying.
