Liam Payne is going to be a dad!

The British singer and his girlfriend, former Girls Aloudmember Cheryl, are expecting their first child, PEOPLE confirms.

Although the couple have yet to officially announce the pregnancy, the mom-to-be let her baby belly do the talking on Tuesday when the two stepped out for the St. James Christmas Carol Concert in London.

Cheryl, who wore a fitted olive green dress and black thigh high boots, let her bump peek through her black trench coat.

Payne, 23, and Cheryl, 33, began dating late last year.

The former One Direction member and X-Factor judge — whose divorce from Jean-Bernard Fernandez-Versini was finalized in October — met when Payne competed on the show in 2010 with his future bandmates.

The couple made their red carpet debut in May at Eva Longoria’s Global Gift Gala in Paris, where Cheryl was awarded the Global Gift Philanthropist Award. Since then, they’ve been open about their affection for each other on social media.

“I saw them together and we had a really nice dinner. They were on good form,” Simon Cowell told The Sun in April. “They’re like two little chipmunks madly in love. But importantly they both seemed very happy over here and very relaxed. I’m happy for them.”
