The couple were pictured looking cosy in the black and white snap Neil posted this evening, in which the Strictly pro could be seen planting a tender kiss on his partner’s forehead.
They posed for the loved-up picture in the dancer’s kitchen.
Neil simply captioned the adorable photo with an orange love heart emoji.
Luisa, who is a dancer and a model from Medellin, Colombia, also took to her own Instagram page to share a Boomerang clip of Neil repeatedly kissing her neck in an elevator.
He was questioned by a fan at the time: “Are you still single?”, after he and fellow BBC star, Katya, split.
The former couple tied the knot back in August 2013 after five years of dating.
Neil responded to the query, simply with: “Nope,” alongside an image of him riding a bike.
Another Instagram user asked him: “How you feel today?”
