Ralph Fiennes and Lady Amanda Harlech
Since this is a list based on British celebrities from the UK, there will be more than a few actors from Harry Potter. Here, we have Ralph Fiennes, who played the villainous character, Lord Voldemort in the film series. It looks like Fiennes isn’t as evil as his character because he has been committed to Lady Amanda Harlech since 2007.
Harlech is associated with the fashion industry, having worked in a Gap advertising campaign and served as a senior stylist for Chanel. On the other hand, Fiennes is quite busy with his upcoming work that includes The King’s Man, No Time to Die, and The Forgiven.
