She started off her night looking chic yet sexy, with a hint of sideboob visible under her daring black top but things didn't end well for Pixie Lott.

For as the night went on she flashed more and more flesh until embarrassingly, her breast tape, used to keep her top in place, could clearly be seen.

It was a mortifying fashion faux pas for Pixie, 24, who looked bleary eyed as she made her way out of Cirque Le Soir nightclub with pals in the early hours of Thursday morning.

A whole LOTT on show! Pixie embarrassingly revealed her breast tape as she left Cirque Le Soir nightclub in London in the early hours of Thursday morning

Lott left the club around 3.30am, holding hands with one of her female pals but didn't appear to notice that she was showing more than she bargained for.

Even though by that stage of the night she had thrown on a black jacket over her racy outfit, it failed to cover up Pixie's wardrobe malfunction.

Things started off better for the beautiful blonde when she attended a bash for Notion magazine at restaurant venue STK on Wednesday evening.

The chart star dazzled fans in the cheeky number, which featured a halter-neck back and utterly sleeveless design.

She accessorised with a simple black clutch bag and plenty of smokey make-up around her eyes.

Opting for a more adventurous hairstyle, she had clearly applied some wet-look get for a more high-fashion inspired look.

Continuing to amp-up her sex appeal for the evening, she also sported some lace-up shoes, which certainly helped the singer/songwriter garner plenty of attention.

Smouldering for the cameras, she posed up a storm as onlookers got an eye-full.

However, it wasn't all perfect - as she also showed a clear tan line across her back.

In a recent interview with Notion magazine, the former Strictly Come Dancing contestant opened up about her nearly five-year long romance with her man, Oliver Cheshire, admitting that she gets frustrated over the attention that accompanies it.

'Honestly, people are obsessed with it!' she pointed out, when asked about marriage.

'I don't know, I always get asked "when are you getting married?" As soon as I started going out with Oliver I was asked it, and I still get asked in it every interview.

'I don't know why that is, maybe it's just something that people want to hear about, I don't know. I think male celebrities probably don't get asked it as much.'

'I'm alright with it,' she adds of the love life speculation. 'I'm quite easy-going; I just go with the flow, because I do get asked the same questions over and over.

'But it's just funny, because it's never something I get asked by my friends, who are all the same age as me. They would never even think about it at the moment.'

And, perhaps more tellingly, in a recent interview in Marie Claire she admitted it'll be a while before they do walk down the aisle.

She told the magazine : 'I love small weddings in a different country, but I like massive ones in England, so maybe I'll have two.

'But I'm not thinking of getting married yet because I'm still so young.'

Her relationship has always inspired her music, and with the star currently working on her new album in Los Angeles she promises they'll be more love songs on the new record.

'When I first starting writing my first album I was like, 14, and didn't really know what a real relationship was, or what the ups and downs are like, and now from being in a long term one I know how that feels.

'So that definitely gives me ammo to write songs and make them more relatable,' she told Notion.

Describing her new material, which follows the release of her Motown influenced record last year, as a return to a 'big pop sound,' Pixie teases that she's planning some exciting collaborations, with the album set to be released later this year.
