Naomi was hardly recognisable underneath all of her gear, but she managed to still look amazing.
She captioned the photos: "Safety First NEXT LEVEL. Thank you @lindaevangeslista Full video coming on my YouTube soon…"
This time last year, Naomi and Liam Payne were rumoured to be dating.
The model and the former One Direction star, 26, sparked speculation of a secret relationship after a series of flirty social media exchanges. In January, Naomi commented on an Instagram photo of Liam, calling him a "beautiful soul."
"Takes one to know one," the singer replied, adding a kiss emoji.
Days later, Payne commented on a selfie of Campbell, calling her "perfection."
"Perfection in a person [rose emoji] don't give me those eyes," Payne wrote along with eyes and a kiss emoji.
A source told The Sun Online: "They fell in love with Ghana when they were there last winter, and are already buzzing about going back there after being invited by the high-profile new friends they have made.
Liam’s has a son with British pop star Cheryl Cole, 36.
