She recently admitted to spending £1 million on a crystal bath, so it’s no wonder Tamara Ecclestone has been looking for some extra work.

Not that the daughter of Britain’s fourth richest person needs any help in the financial department, but she’s a girl who likes to earn her own money too.

So Tamara got to work by modelling the latest lingerie collection by Ultimo and posed in an array of sexy satin smalls.

The 27-year-old slipped into a midnight blue balcony bra and knicker set as she posed on a four post bed, before changing into a purple and black lace camisole set.

The daughter of billionaire F1 boss Bernie Ecclestone glammed up the ensembles with dangling earrings and bracelets – and of course some sheer stockings.

The brand’s new collection features Ultimo’s first ever camisole, which has been described as ‘bedtime luxury’.

It’s Tamara’s second photo shoot for the lingerie company, after first appearing in Ultimo’s knickers in May this year.

And she seems to have become boss Michelle Mone’s latest muse for the collection.

Kelly Brook and Mel B have also previously been spokeswomen for the brand, which favours celebrity models over catwalk professionals.

Meanwhile, Tamara arrived back in London yesterday after having been abroad for two weeks and tweeted that she had a lot to do.

She then updated her Twitter followers last night: ‘Just went for dinner at Benihana yum! Now more tv to catch up on.’

Before arriving back in the UK, Miss Eccelstone had been living the Hollywood lifestyle in Los Angeles, where her sister Petra was also spending time with her new husband James Stunt.

Tamara was joined by her boyfriend Omar Khyami too and gushed about how much she loved the California lifestyle.

‘I would love to come over here and spend three or six months of the year here, I would love that, like when it’s raining in London’, she said.

‘It’s such nice weather, I love it. It makes such a difference.’

The socialite had also been holding meetings with American TV executives while Stateside and has a three-part reality show, titled Tamara’s World, airing in October.
