In addition to the digital exchanges, the couple has been snapped by The Daily Mail on a date night together.
They were attending a Davido Adeleke gig at London’s The O2 Arena, with a source telling the UK publication: “Liam and Naomi were keen to keep a low profile. They entered and exited the arena via the back door and were quickly whisked up to a VIP suite on Level 3. After the show they left together in the back of a blacked-out green Range Rover and Liam was seen putting his arm around Naomi's waist.”
Payne announced his split from Cheryl Cole, 35, last July and the couple share one-year-old son Bear together. Campbell is also single, having broken up with her most recent boyfriend, British rapper Skepta, 36, in August of last year.
