Liam and Cheryl, who have been dating for a rumoured five months, left celebrity hotspot Sexy Fish in Mayfair to a sea of photographers.
One Direction star Liam held onto Cheryl's hand as the couple made their way into a taxi.
Cheryl wore a tropical sunset print satin bomber jacket retailing at more than £1500 by Saint Laurent, which she paired with leather culottes and a red vest top.
Reports last weekend claimed the couple have taken the next step in their relationship and moved in together in Liam's multi-million pound mansion in Calabasas, Los Angeles.
A source told The Sun: "Cheryl and Liam are getting more serious by the day. They are so happy together and head over heels. It is definitely the real deal. In fact I wouldn't be surprised if Cheryl had her first child with Liam."
Meanwhile, Simon Cowell also recently spoke about their relationship, saying: "I saw them together and we had a really nice dinner. They were on good form. They're like two little chipmunks madly in love. Literally, they were so cute."
Elsewhere, former Girls Aloud star Cheryl also quit The X Factor last week, stepping down as a judge on the ITV talent show to focus on her music career.
She said in a statement: "I have had such an amazing experience being a judge on The X Factor. I have learnt so much and enjoyed nurturing talent but I've missed making music and am excited to be recording again. I want to thank everybody I have worked with along the way, especially Simon who I love to bits. I hope the show continues to produce stars and I wish them all the best."
