A source told The Daily Star: “Calvin has discussed the possibility of marrying Taylor with his parents. It is still early days but none of his team would be surprised if he went down on one knee this year.
“They are both very solid at the moment and happy. They have had a fantastic few weeks together over the Christmas period.
"It was the first time they have had a large amount of time together, mixing time alone with family activities, and it went brilliantly.
“Calvin has never been more content and is really smitten with Taylor.
"She's also head over heels and has never been in a relationship like this."
They added: "One of Calvin's team has been talking about where to purchase bespoke rings which has prompted people to feel that an engagement is close."
The couple began dating in February 2015 and have been inseparable ever since.
