The US pop singer began dating the Conversations With Friends star, Joe Alwyn, in late 2016 after they were rumored to have crossed paths at that year's Met Gala.

Axar.az reports that the Sun claims the pair have been secretly engaged for a "few months" but have only told their inner circle, with no plans to go public.

It's understood they haven't told some members of their team.

A source close to Joe told The Sun: “Taylor and Joe are incredibly happy and very, very in love.

“They’ve actually been engaged for a few months but have only told their inner-inner circle basically immediate family, and trusted, very old friends. Everyone has been sworn to secrecy, too."
