Chloé Madeley parties the night away in a low-cut LBD

She's recently had to defend herself over criticism that she only gets handed television and modelling opportunities because of her parents.

But last night Chloé Madeley looked like she didn't have a care as she let her hair down and partied with her brother Jack.

The 21-year-old also proved why she has been picked to promote lingerie as she donned a very revealing little black dress.

Richard and Judy's daughter has become a regular on the London party scene as she carves out a career in TV and modelling.

Chloé claims she has the talent to succeed despite her name. She told BBC Breakfast: 'When it occurred to me that I wanted to go into TV, it was a proper decision because if I said yes the nepotism claims would start storming in.

'I had to ask myself will I still want to do it after all the critics say that and I hope I'm here in the long run.'

'The name does help me get mentioned in meetings but it's still really hard,.

'If I'm no good I'm going to be gone by next year.

'But now I do understand it's part and parcel. If you say you want to be in the public eye you need to be willing for people to criticise you.'

Chloé and brother Jack appeared determined to enjoy themselves at the launch party for Sony's new line of BRAVIA LCD televisions in East London last night.

She had some stiff competition in the glamour stakes from topless model and former I'm A Celebrity! contestant Nicola McLean.

Former Blue Peter presenter Konnie Huq also made an appearance.

As well as appearing on her parents former Channel 4 show, Chloé has presented four episodes of Big Brother's Big Mouth with sibling Jack.

She also presents a section on her parent's new chat show on the Watch channel called Chloe's Angels, where she covers news from the red carpet at film premieres.

The star has admitted, however, that she had to carefully consider whether to do the modelling shoot for Ultimo when the company approached her.

Chloé, who posed for lad's mag FHM last year, said: 'Initially when they asked me I didn't think I was in shape enough or model-like enough to do it.

'But when I told my parents they thought it was brilliant. Ultimo is a huge, huge brand and you should be really flattered they have asked you.

'I mulled over it for a couple of days and then said, "Yes, I'll give it a shot". I only had three days to diet and exercise and prepare.'
