Tulisa Contostavlos embarks on a night out with Rochelle Wiseman and Vanessa White


'I'm the sixth member!': Tulisa Contostavlos embarks on a night out with Saturdays stars Rochelle Wiseman and Vanessa White

She's said to be working on new material away from the rest of her group N-Dubz, but the assumption was that she was working alone.

However, as these pics suggest, perhaps Tulisa Contostavlos is in cahoots with The Saturdays to produce some new music, especially after joking that she'd joined The Saturdays as their sixth member.

The X Factor judge hit a few hotspots during a night out in central London with Rochelle Wiseman and Vanessa White from the popular girlband.

Tulisa, 23, risked catching a chill
in a rather revealing black mini dress with lace detailing, and a pair
of black ankle boots.

In fact, all three ladies were
dressed in typically English style, braving the recent dip in
temperature to show off their toned legs.

Rochelle, 22, kept her slim figure mostly under wraps in a gold bandage dress from celebboutique.com with a pair of studded black heels.

While bandmate Vanessa was the only who sensibly wrapped up a little covering her shoulders with a patterned jacket.

Although, underneath, she wore a tiny denim dress and black ankle boots, similar to those worn by Tulisa.

The
girls kicked off their night at the Nobu restaurant on Berkeley Street
in Mayfair – an eaterie where many a celeb dines out on a weekly basis.

In
fact, Lisa Snowdon was also pictured leaving Nobu last night – the TV
presenter, who celebrated her 40th birthday earlier this week, wore a
black dress with an unusual shiny panel covering the front, followed by retail heiress Chloe Green.

Meanwhile,
Tulisa and The Saturdays girls held hands in a show of unity as they
left the oriental restaurant and headed up to Soho where they spent some
time at Movida before heading on to Jalouse.

Vanessa
walked arm in arm with Tulisa's PA Gareth Varey, who appeared a little
worse for wear with his shirt unbuttoned almost to his midriff.

Tulisa joked with onlookers that she'd joined The Saturdays as their sixth member.

Earlier this week she confirmed that she will be releasing a solo single in the next few months.

With
her group N-Dubz on hiatus and her recent split from bandmate and
boyfriend Richard 'Fazer' Rawson, it's the perfect time for Tulisa.

She told London radio station Capital FM: 'I've got my single ready now to release. I'm going to be shooting a video soon.

'Haven't got a set date but I'd say within the next two months definitely.'

And
despite singing urban songs with her N-Dubz bandmates Fazer and
Costadinos 'Dappy' Contostavlos, Tulisa's solo sound will be a little
different.

She
explained: 'It's very me but maybe not what people would expect
genre-wise. It's one of those tracks that you don't get bored of.'

Aside
from her solo work, Tulisa is rumoured to be duetting with her 'little
muffins' Little Mix on a track for their debut album.
