Ellie Goulding and Cressida Bonas lead the style pack at the Years & Years album launch

British band Years & Years proved that they've got friends in high places as stars including Ellie Goulding and Cressida Bonas showed up to their album launch party.

The electronica trio, whose single King reached the number one spot back in March, celebrated the launch of their debut album with a star-studded party at One Mayfair on Wednesday night.

Chart-topper Goulding was on hand to lend her support, showing up to the party with boyfriend Dougie Poynter in tow.

The 28-year-old wore a loose-fitting print minidress while the McFly star wore an open blue print shirt and black skinny jeans.

Prince Harry's ex-girlfriend is also clearly a fan of the band, mingling with stars including Freddie Fox and Ben Whishaw as the party got under way, with guests sipping on Patrón Tequila cocktails including Patrón Take Shelters and Patrón Long Margaritas.

During the party the band - made up of Emre Turkmen, Olly Alexander and Mikey Goldsworthy - was presented with a Platinum Sales Award for their hit single from manager Martha Kinn.

Back in March, Years &Years announced that their debut album will be called Communion and will be released this week.

In an interview with Digital Spy, frontman Alexander admitted that "all the songs are about sex or relationships."

He added: "It was important for me to get some male pronouns in some of the songs. So I did it for 'Real' and 'Memo', and then one song on the deluxe. It is kind of sad to me that we don't have gay popstars singing about men using a male pronoun, but that could change hopefully."
