According to The Sun, the 29-year-old model has been sharing her feelings about her life with the film director.
Ainsley said: "Guy's my soulmate. I love every moment we spend together. I can't see that ever changing."
She added: "I lived on my own for three years and I loved having my own space. But yes, now things have changed and I've moved to London. It was very organic, we were spending all our time together so it made sense.
"We love to watch films, read to each other, cook together. My dad teaches film and has done for 40 years so I've really grown up in a movie household.
"All the walls are covered in movie posters and many of the evening meals at 7.30pm revolved around film discussions. So I come from a film-loving family. We definitely have that in common."
