The couple, who ended their relationship in July after a year together, were spotted enjoying a secret romantic weekend together over the Easter break.
Millie, 26, and Liam, 23, spent the Bank Holiday in the Lake District, making the most of the countryside and having a cosy takeaway on Saturday evening.
Following the breakdown of their romance a year after they won Love Island in 2021, Liam went on E4 show Celebs Go Dating, while Millie has recently been rumoured to be dating Gogglebox star George Baggs.
However, a source close to the pair has told MailOnline that the couple have been talking again, meeting up in secret and are working through their previous issues.
An insider said: ‘Millie and Liam have been talking again, but it’s early days for them.
‘They weren’t expecting to get back together after their breakup was so painful for them both, but months have passed, and they still couldn’t stop thinking about each other.
