Liam Payne joins glamorous girlfriend Kate Cassidy, Vogue editor Edward Ennin at a glitzy birthday bash

Liam Payne joined glamorous girlfriend Kate Cassidy at British Vogue editor Edward Enninful’s birthday party in London on Friday.

The 23-year-old beauty looked sensational in a skintight pink dress when she arrived at the star-studded The Maine Mayfair event.

Her gown sported ornate sleeves, as well as cut-outs at her slender waist and an asymmetrical hem.

American-born Kate, who started dating the pop star in October, sported a glamorous palette of makeup and swept her blonde hair back into a shiny ponytail.

She completed the look with shiny silver heels and carried her essentials in a matching clutch.

Meanwhile, Liam donned a black leather biker jacket that he teamed with some quirky cream hems.

Slipping his feet into chunky boots, he sported a designer beard and had his hair perfectly coiffed.

The night comes after the couple supported the launch of the Vogue hotshot’s new book earlier this week.

The former X Factor star looked in high spirits as he snapped photos at various points on the night he celebrated A Visible Man with many notable guests at the event hosted at the posh Cut restaurant at 45 Park Lane.

Liam wore a black tank top under a gray blazer with slim black lapels, as well as a matching gray plaid vest from Dolce And Gabbana.

Meanwhile, Kate sizzled in a plunging black blazer as she posed up a storm for the cameras.

While rubbing shoulders with her fellow A-Listers, she also snapped a photo with a cute puppy while making faces for the camera.

Posing with a cola in hand, Liam captioned a story for his 24.9 million Instagram followers: ‘Couldn’t be happier at the ATM. It finally looks like things are coming together…

It comes after the two enjoyed a Valentine’s Day date night at Longleat and Safari Park.

Kate wowed in a cut-out dress with a thigh-length leg slit, and styled her bright blonde hair in soft waves. She finished off her look with a pair of barely there heels and carried a small crocodile print bag.

Liam opted for a cream satin shirt tucked into a pair of black trousers with Chelsea boots.

Posing for another fun photo, the singer kept it much more casual in a camouflage jacket and cap while visiting the giraffes in the park.

It comes after Liam responded to a troll who claimed his girlfriend is only with him for money.

The singer and Kate made their red carpet debut as a couple at the British Fashion Awards before Christmas.

But it seems not everyone is sold on the relationship, as a fan sent a DM warning Liam that Kate was after his money earlier this week.

Date Night: His appearance comes after spending Valentine’s Day in love with his girlfriend Kate Cassidy, on a lavish date night in which the couple dressed to the nines.

Liam responded by taking a screenshot of the message and posting it to his Instagram Stories and gushing about his new romance.

He said: ‘I have to say you could tell me anything and I couldn’t convert, I never felt a love like I do for Katelyn.’ We make each other better people.

Defending her against the gold-digging accusations, he said: “If it was just for the money, I would give it all to her.”
