Real-life Game of Thrones sweethearts Kit Harington and Rose Leslie are about to tie the knot as the couple is now engaged. The 30-year-old star has proposed to his former co-star after being together for five years.

Harington and Leslie started dating in 2012 when they met on the set of the HBO series, where the 30-year-old actress played the role of Ygrette. Although they just made their relationship official in 2016, the pair has been together for a long while now.

The engagement’s announcement

"They’re yet to set a date,” a source told the Sun.

However, it was said that Kit Harington and Rose Leslie already announced their engagement to their families and friends last week.

The English actor has wanted to marry the Scottish actress for so long. But, he would like to settle things first and made sure that they have a house to live in. Speculations are rife that Harington and Leslie are already engaged since they moved in together in January.

The “Game of Thrones” stars are now living in their £1.75-million ($2,3 million) mansion located in East Anglia. “I've moved in with my other best friend Rose, so I'm very happy,” the “Pompeii” actor told James Corden in June. He even revealed that everything was going well for them. In fact, Leslie now has a lot of ideas for their new home.

Harrington also disclosed he told Leslie that it is important for them to have their own space. He wanted her to feel that the house is also hers, so she should never feel like she just moved into his abode. He wants her to move and change everything she wants. The couple purchased a seven-bedroom house with a medieval theme.

The moment Harington fell in love with Leslie

Kit Harington and Rose Leslie were often surrounded by engagement rumors after they made their first public appearance together.

They denied the assumptions in July, after Life & Style magazine claimed that they are already planning for their wedding. In an interview with L'Uomo Vogue in 2016, Harington talked about how he fell in love with Leslie on the set of “Game of Thrones.”

The pair hid their relationship for four years before they finally made it official in 2016.

Harington admitted that it was just very easy to fall in love with his girlfriend. While they were staying in Iceland for three weeks for the production of the hit HBO series, he fell in love with the country’s beauty and the light of the “North magic.” "If you are attracted to a person and in fiction, she is your love interest, it becomes easy to fall in love," he said.
