Joe Jonas and Sophie Turner join Ashley Graham and Nick Jonas as they arrive for their engagement party in NYC

SOPHIE Turner and Joe Jonas are all smiles as they arrive at their New York engagement party, joining a host of A-list pals, including Joe’s famous brothers.

Game Of Thrones star Sophie, 21, showed off a giant sparkler she’d acquired from pop superstar Joe, 28, during their recent holidays together as they headed into their venue.

Sophie wore a buttoned-down silk shirt with a matching jacket and trousers – twinning with her hubby-to-be.

Joe was also wearing a black and white suit with a hound’s tooth pattern, and didn’t seem to mind that his lady was towering above him in huge platform heels.

The pair have been dating since November 2016, but they did not go public with their romance until January this year.

Having met through a mutual friend and first got close after attending a 2016 Halloween party, with Sophie dressed as a rabbit and Joe as a dog.

Being the alter-ego of Sansa Stark and one third of a huge boy band respectively, the pair attracted some major stars to their engagement bash, which was held at the restaurant Mamo.

Nick Jonas, Joe’s 25-year-old brother and an ex of Miley Cyrus and Lily Collins, seemed to reveal he is no longer single by attending the event with a beautiful model.

Looking sheepish and avoiding being seen, Nick was snapped hanging around just inside the venue waiting to leave.

With his was scowling beauty Georgia Fowler, a model whose Instagram pics he’s been liking and commenting on for a good while.

New Zealander Georgia, who like Nick is 25 and is a Victoria’s Secret Angel, wore a strapless blue dress with white detailing to the party but didn’t wear a smile as the evening drew to a close.

However, Nick’s brunette date – who briefly dated Harry Styles in 2015 – got into the same cab as her companion, who used to be known as a Christian heartthrob and wore a purity ring.

Nick has been linked to a whole host of famous females over the last few years, including Kendall Jenner, another ex of Mr Styles.

Previously he romanced Delta Goodrem, Samantha Barks and Selena Gomez, who has just rekindled her rocky relationship with Justin Bieber.

Georgia wasn’t the only clothes horse gracing Sopie and Joe’s big celebration last night.

Plus size model Ashley Graham, 30, arrived with her husband Justin Erwin and the loved-up pair held hands as they marched inside.

Beautiful Ashley has been getting more and more high-profile jobs following the launch of her “swimsuits for all” line.

And she looked drop-dead gorgeous in a Chinoiserie-inspired black mini-dress, showing off the tan she’s picked up from her recent holiday.

Ashley, who married Justin in 2010, turned 30 at the end of October and was away in Costa Rica for the celebrations.

But she hurried back to see her pals Joe and Sophie – and of course, the third Jonas brother Kevin, without whom the party would not have been complete.

Dapper Kev, 29, brought along his wife Danielle, 31, who he’s been married to since 2009 and stars with in reality show Married To Jonas.

The pair must have got a babysitter for their daughters Alena, three, and Valentina, who’s one, so they could attend.

Sophie and Joe haven’t dropped any hints about when they’ll wed just yet, but it’s a safe bet the two other Jonas brothers will be Best Men.

And Game Of Thrones’ Maisie Williams, currently filming the ninth series in Belfast, is definitely likely to be a bridesmaid considering her close bond with Ms Turner.
