Lottie Moss showcased her friendship with Arabella Chi as the two headed home after attending the one year anniversary of PrettyLittleThing's London showroom on Thursday evening.

The model, 26, looked a little tired after the night of celebrating as she held hands with the Love Island star. 

The star, who is the sister of Kate Moss, flashed plenty of skin as she opted for a pretty bra top with a plunging neckline. 

She teamed the piece with a matching semi-sheer skirt and boosted her height with white stiletto heels. 

Meanwhile Arabella put on a very leggy display as she wowed in a little white silk dress and baggy white leather boots. 

She completed her look with a beige blazer jacket and a tiny sparkly handbag. 

The Love Island stars were out in their masses, as the pair were also joined by Demi Jones, Hannah Elizabeth and Ella Barnes for the evening. 

Demi opted for a little black halterneck dress, before turning around to reveal the PrettyLittleThing printed across her bottom in white. 

She completed the look with some black strappy heels and a little black handbag, while her brunette locks were tied up in a high ponytail. 

Meanwhile Ella, who recently joined the cast of TOWIE, kept it casual in a faded denim co-ord with a black crop top. 

Hannah Elizabeth showed off her enviable curves in a teal figure-hugging long-sleeve jumpsuit, as she styled her blonde locks in voluminous curls. 

Made In Chelsea star Liv Bentley flaunted her slender legs in a very short black plunging playsuit with white edging. 

She paired the look with some simple white heels and an oversized blazer which she hung over her shoulders. 

Elsewhere Georgia Steel opted for a black faded denim shirt and matching jeans as she smiled in snaps after her recent break up from Love Island flame Toby Aromolaran. 

The couple, who finished fourth place in the final, have called time on their whirlwind romance just one month since they departed the villa together.

It was Toby who called it quits on the pair's romance, which came as a complete shock to Georgia. 

Abi Moore made sure to flash plenty of skin as she displayed her toned abs in a nude and black floral wrap dress. 

The TOWIE crew were also out in force as they posed for snaps together. 

Amber Turner cut a sophisticated look in a nude blazer and matching pleated skirt. 

Putting on a leggy display in the ensemble, she tied the outfit together with a black crop top, belt and some knee high black leather boots.  

Dani Imbert showcased her ample cleavage in a white bodycon strapless dress as she was joined by Junaid who added a pop of colour in a pale pink jumper. 

Twins Jess and Eve Gale also left the party together as they each showed off their surgically enhanced assets in their skimpy tops. 

Jess opted for a cream cropped vest top which she paired with a barely-there sheer print skirt. 

Holding hands with her sister, Eve donned a black pin-striped co-ord, after recently revealing her surprise new romance with Demi Sims.

Eve revealed that she and Demi had a flirty friendship for years but have now enjoyed their first date together and are getting on like a house on fire.

A source has told OK!: 'Eve and Demi's date may have come as a surprise, but they've been texting a lot behind the scenes. They quickly realised just how much they liked one another and the attraction took off from there.

'It all started as a friendship and it's allowed them to grow naturally. They know each other well and are always giggling and laughing. Everyone around them is pleased to see them happy.'

Demi was joined by her sister Frankie for the evening, as she turned heads in a Louis Vuitton denim ensemble. 

Meanwhile Frankie opted for a green gradient satin two piece.  

The Love Island boys were looking dapper for the night as Antony Danyluk kept it stylish in a khaki green suit and open white shirt. 

Chris and Mitch Taylor were also seen attending the event, as they reunited with their former flames from the show.
