WATCH: Sorisha Naidoo's heartmelting moment as Vivian Reddy surprises her with a huge diamond ring

South African reality TV star Sorisha Naidoo excitedly shared that her billionaire husband, Vivian Reddy, gave her a sweet and stunning surprise - a huge diamond ring.

The businesswoman posted a heart-warming video on Instagram of what seemed like a normal couple’s date, which quickly turned into a surprise as she was gifted the ring.

Naidoo expressed gratitude to her husband not only for the gift but for his unwavering love that he always showers her with.

“Thank you for a love that needs no occasion - for surprise flowers in quiet moments, for laughter that lights the room, for a heart that gives freely,” she wrote.

She was visibly emotional as she received the gift, and said “wow” before she planted a kiss on her husband’s lips as he assisted her with putting on the eye-catching ring.

“The Real Housewives of Durban” star further expressed how grateful she is to share and experience this life with Reddy.

“I am treasured, adored and endlessly grateful to walk this life with you. You are the unexpected in my day and the calm in my night. You are my hopeless romantic, and I love you for it,” she added.

Reddy, a philanthropist and businessman, commented on her post, sharing that he is also grateful just as much to share the journey of life with her.

“Your words move me, my love. You are my strength, my joy and the love of my life. Walking this journey with you is the greatest gift I will ever know,” he commented.

The couple tied the knot in 2003 and share two children together.

While Naidoo was labelled a “gold-digger” for getting married to a man who is 23 years older than her, she says it troubled her at first, but she eventually got used to the name-calling.

“I welcome it. It used to haunt me, but I don’t care now. I always earned a reasonably good salary, and I’ve never stopped working,” she said at the time.

Although the public doubted whether their love was real or not, the couple's love thrived and blossomed into something so beautiful that a lot of people admire today.

The pair also give fans a glimpse of it now and again on social media through dedicated and heartfelt posts.

Just recently, they celebrated their son, Sai’s 17th birthday and Reddy shared a post on Instagram thanking his wife for giving birth to their son.

“My love @sorishanaidoo thank you for blessing this world with such a kind, caring and loving soul 17 years ago. Our son’s beautiful heart is the truest reflection of you,” he captioned his post.
