Hiddleston confirmed the couple’s engagement in a recent interview with the LA Times, but kept tight-lipped about the romance, simply saying, “I’m very happy” and nothing more.

Tom and Zawe spoke up about a possible engagement earlier this year when they appeared at the BAFTAs earlier this year, after which she was pictured with a huge diamond sparkler on her ring finger in a photo shared by host AJ Odudu.

The couple confirmed their romance during a steamy PDA-packed vacation on Ibiza’s beach last September, before making their red carpet debut together at the Tony Awards in New York City.

It was revealed last year that the couple had moved in together after months of romance rumors, and now they would be living together in Atlanta, Georgia.
