Liam Payne, Cheryl Fernandez-Versini spotted on date in London

LONDON, March 10 (UPI) -- Liam Payne and Cheryl Fernandez-Versini were all smiles on a dinner date Wednesday in London.

The 22-year-old One Direction singer and 32-year-old X-Factor U.K. judge were spotted holding hands as they left blogger Lily England's 30th birthday party.

Payne and Fernandez-Versini both wore all-black outfits to the fête at Salmontini restaurant. Fernandez-Versini's mom, Joan Callaghan, was seen with the couple at the event.

The One Direction singer first met Fernandez-Versini when he auditioned on The X-Factor in 2008. He appeared on the show again as a contestant in 2010, and has reportedly been dating the 32-year-old since late 2015.

"[It's] not serious ... but they're enjoying things," a source recently told Us Weekly. "[They hate that word] is out there, [but Liam is] kind of relieved at the same time because now they don't have to be paranoid about getting caught."

Payne split from his girlfriend of over two years, Sophie Smith, in October. He dedicated a post to Fernandez-Versini on his Instagram account Tuesday, writing, "Happy #internationalwomensday to my favourite woman in the world. Hope I make you as happy as u make me X."

Fernandez-Versini, meanwhile, was married to Ashley Cole from 2006 to 2010 and is in the midst of a divorce from Jean-Bernard Fernandez-Versini. She returned to The X-Factor in Season 11 and released her fourth studio album, Only Human, in 2014.
