Rebel flaunted her physique in a black and white dress, complete with buttons along the front.

She styled her blonde hair in curls and let her natural beauty shine, opting to wear a neutral palette of makeup for the outing.

Jacob also looked stylish in jeans, a white T-shirt and black blazer as he leant his arm on the wall alongside his girlfriend.

He completed his ensemble with a pair of brown shoes and couldn’t wipe the smile off his face before he planted a kiss on Rebel’s cheek.

Meanwhile, Rebel has been on a health journey this year, losing at least 18kg (40lbs or 2.8 stone).
