The former Girls Aloud star posed happily for photographers as she attended the Fayre of St James Christmas Carol Concert in London, in aid of Cheryl's Trust in support of The Prince's Trust. The recently-divorced star looked stunning in a tightly fitted khaki dress which clearly showed off her blossoming figure.
The happy duo have yet to officially comment on the rumours about their private life which have been flying for the past few months. But despite taking time out of the limelight, the pair have been active on social media recently - with Cheryl taking to Twitter frequently in the past few days to discuss her thoughts on this year's I'm a Celebrity show.
The 33-year-old star recently spoke to HELLO! about how she loves nothing more than chilling in her "jammies" during the weeks when the hit TV show is on.
"I like to relax, hot chocolate and watching the telly," she told us. "I'm A Celebrity is my favourite few weeks. Just chilling at home, no hair and makeup, in my jammies and dressing gown with the dogs sitting on the sofa," she said.

The singer also revealed that she loves having her house packed full of family, especially her young nieces and nephews.
"I've got millions of nieces and nephews now," she told HELLO! "It is chaos but I love it. I don't like silence. I like chaos."
Cheryl and Liam have both previously spoken about their desire to start a family. Speaking in August 2014, the former X Factor star told GQ magazine: "I'd love kids. I'm obsessed with babies. Of course I've thought about baby names. A million times! I like Alfie for a little boy. I know that's what I was put on this earth to do. To be a mother."
For his part, One Direction star Liam, 23, has also said he would love to be a dad. Speaking to Magic Radio in August 2015, he said: "I wanna have kids when, you know, I have the time, but at the moment life's so busy, and I wouldn't want to commit to something like that when I haven't got the necessary time for it yet. That's my careful planning ahead!"
