Kristen Stewart's ex-boyfriend Robert Pattinson and his fiancée FKA Twigs' engagement is still going strong as the couple opted for a low-key relationship. They are not very visible lately and their last sighting together was during the London premiere of "The Lost City of Z."

When their engagement was first announced, fans of the "Twilight" stars were vocal about their frustration of the relationship as they are still hopeful that the Robsten tandem will still continue. More than a year after and a series of relationships with other women, Kristen Stewart is still being linked to the engaged actor.

Unfounded rumors about a broken engagement have been aplenty but nothing has triumphed to separate Pattinson and the British musician. The 30-year-old actor has been so busy lately with several films in the works as per Celebeat. He appeared with Nicole Kidman in "Queen of the Desert." His film "The Lost City of Z" will be released in selected theaters on April 21 and will then expand.

He has several upcoming movies too. For the 2017 production, he has three movies - "Damsel," The Trap," and "Good Time." For 2018, he will be filming "High Life" and "Idol's Eye." No wonder, their wedding date has been postponed. There was no update on the date but the pair might wait till he wraps up filming. Although it will take a long time, the couple is enjoying each other.

LA Weekly reported that the director of the Brad Pitt-produced film was all praises for Pattinson because of his realistic portrayal of his role. Director James Gray said that about Kristen Stewart's ex-boyfriend

Director Gray said that the actor is generous enough in doing his role. He has to grow an enormous beard to play his role as the director envisioned it to be. The actor has moved away from the wholesome, heartthrob roles and transformed himself into some serious actor.

With his busy schedule, a wedding might not happen soon. Stay tuned for updates on Robert Pattinson and FKA Twigs wedding date.
