Princes William and Harry's cousin Lady Amelia Spencer has gotten engaged to her long-term boyfriend Greg Mallet in South Africa.

Princess Diana's niece met her fiancé-to-be at the University of Cape Town, and the pair have been together since.

Real estate agent Greg proposed to Lady Amelia with an incredible ring days after his 30th birthday. The soon to be son-in-law of Earl Spencer popped the question at Clouds Wine & Guest Estate inStellenbosch, South Africa.

Greg announced the news on Instagram, with a sweet tribute to his new fiancé.

"So this was the best day of my life. 22nd of July 2020, I asked the love of my life to spend the rest of her life with me and she said YES,"he wrote to his followers."Couldn’t be happier and I love you with all my heart@ameliaspencer15."

Among fans to share their delight at the news was Amelia's older sister Lady Kitty Spencer. 'BROTHER-TO-BE!!!! Happiest times ahead!!!!,' she commented on Greg's sweet post.

Lady Amelia was in attendance at Prince William's wedding to Kate Middleton at Westminster Abbey in 2011, alongside sisters Eliza and Kitty.

Although she was absent from Prince Harry's wedding to Meghan Markle in Windsor in 2018, her sisters did attend.

Amelia's father Charles paid tribute to the happy couple with his own social media post. He posted a picture of the couple on Twitter, alongside a heartfelt caption.

'So happy for my daughter, Amelia, engaged to her boyfriend of 11 years, Greg – it's wonderful to hear them both so excited about their future,' Earl Spencer wrote to his 14 thousand followers.

'Sending them both love, and every good wish for their life together. I love that Greg asked my blessing before proposing. Very sweet.'

Amelia is one of Earl Spencer's seven children. Along with twin sister Lady Eliza, she grew up with older sister Lady Kitty and younger brother Louis Spencer, Viscount Althorp. The siblings moved to Cape Town, South Africa, in 1995 with their father and mother, Victoria Lockwood, in orderto escape media attention.

Following Charles and Victoria's divorce in 1995, the siblings remained in South Africa while their father relocated back to the UK, where he resides in his and Diana's childhood home, Althorp House.

Lady Amelia has three half-siblings from her father's two subsequent marriages: The Hon. Edmund Spencer and Lady Lara Spencer from Charles' marriage to Caroline Freud, and Lady Charlotte Diana from his marriage to third wife Karen Gordon.
