Liam Payne goes casual as he joins girlfriend & Harry S at 1D's (awful) hairstylist's book launch

He's normally more dapper when he arrives on the red carpet.

However, on Tuesday night, Liam Payne went for a more laidback, scruffier look than normal as he brought his girlfriend Sophia Smith to a book launch in London.

The singer and his 20-year-old girlfriend were seen together at the launch of One Direction hairstylist Lou Teasdale’s DIY beauty book, The Craft.

Looking as flawless as ever Sophia kept her evening attire simple, as she wore a black jumper and combined it with black leggings.

Pairing her dark clothes with black open-toed shoes and a small black leather bag, the youngster lifted her outfit out of the murky depths by wearing a fitted beige mac.

She elected to wear minimal make-up and who could blame her, when her natural beauty shone through so brightly.

While his girlfriend shone radiantly, Liam looked a world away from his polished appearance.

The 20-year-old singer wore a bushy beard and woolly head, both of which covered his handsome features.

Looking like he dressed for comfort, Liam wore a black Adidas hoody underneath which he had on a white T-shirt.

Baggy black jeans were the order of the day for the songwriter who, teamed up his bottoms with white trainers.

Liam was not the only One Direction member who opted for the nonchalant look. Bandmate Harry Styles also wore black jeans, which he teamed with a navy blue Calvin Klein jumper.

Despite being in the presence of his own personal hairstylist Harry’s usually well-groomed hair looked messy as he wore a black and white bandana around his head.

Shaggy-haired musician Ed Sheeran was also at the party, soaking up hair and beauty tips.

The Little Bird hitmaker was pictured giving Rizzle Kicks star Jordan Stephens a playful kiss on the cheek.
