Was that the best dress to wear for a big birthday meal? Imogen Thomas dines out in a skintight outfit as she turns 29

Many people would opt for a loose outfit if they knew they were going out for a big dinner with friends to celebrate their birthday.

But Imogen Thomas opted to put style above comfort as she turned 29 earlier this week, pouring her curves into a skintight brown dress as she dined with friends at London's Roka restaurant.

And while Imogen was photographed blowing out the candles on her huge chocolate birthday cake, it seems she may not have indulged in any dessert, as she left the eatery looking as slender as when she arrived.

The pretty strapless minidress featured sequinned detailing on the bust, and Imogen teamed her birthday suit with a pair of black heels and a metallic clutch bag.

Earlier in the day, Imogen tweeted her excitement about her birthday plans, writing: 'Lush surprise...roka! Love this restaurant. Were gonna rockkkkkkk! X'

She then posted a picture of her and banker Adam cuddling up at the dinner table with her friend Emily Jane, along with the caption: '@emilyjane333 @parris_taylor and ads and moi...rocking it xxx'

Imogen and banker Adam, 26, started dating in October following the reality TV star's split from rugby player Danny Cipriani.

And things appear to be going well for the couple, with Imogen even telling friends that Adam could be 'the one'.

A friend of Imogen's told The Sun: 'She has really fallen hard for Adam. He has no ego and treats her like a princess.'

It has been a busy few months for Imogen, who presented segments on ITV programme This Morning over the summer.

And the former Big Brother star also recently revealed she is aiming to make it in the movie industry after landing a role in a big Hollywood film.

While she said she couldn't reveal much about the movie, Imogen did say: 'I want more acting roles to come along. I see that being my future.

'I'd love to do an action flick or be a Bond girl - that would be amazing. That would be my goal. Or to play Lara Croft. Basically, I just can't wait for people to see me in a bit of a different light.'
