Sam Ball is more loved-up than ever with his new girlfriend. 

The former Married At First Sight villain shared a tribute to his love, Kylie Caires, on Valentine's Day, after the pair went Instagram official in January. 

The 29-year-old shared two videos to Instagram Stories showing the couple enjoying a day out together. 

'I didn't see you coming but I am so glad that god placed you on my path. I didn't think my match existed. I was wrong,' Sam wrote. 

'Happy Valentine's Day. Te amo,' he added, meaning 'I love you' in Spanish and Portuguese - the latter being Kylie's native tongue. 

Sam and Kylie, who describes herself as a Portuguese personal trainer, went public with their romance earlier this year, when Sam shared some some sunset snaps of the pair on a date. 

The couple glowed in the evening sunshine and donned workout gear for some cardio training.

Kylie, a fitness influencer, wore a stylish ensemble made up of a turquoise sports bra with black workout leggings, blue tinted shades and perfectly manicured white nails. 

Whilst Sam's outfit was much more simple with a grey t-shirt, black shorts and a baseball cap. 

Sam captioned that post with 'Sunset cardio with my lindo pedaço do céu' which translates to 'beautiful piece of heaven'. 

Relationship rumours started earlier that month when Sam posted a racy picture of the couple spending quality time on Perth beach. 

When approached for comment at the time, Ball refused to confirm whether the couple were an item, instead telling Daily Mail Australia: 'Kylie is amazing'.

Little is known about the brunette beauty however photos saved to her private Facebook page indicate a passion for bodybuilding and fitness.  

She is also regularly sharing photos of her looking glammed up head-to-toe. 

Ball was public enemy No. 1 during MAFS' sixth season when he body-shamed his 'wife' Elizabeth Sobinoff on their wedding day.
