While we patiently await more news about a possible Downton Abbey movie (*fingers crossed*), one of the series鈥 stars has just announced an exciting IRL romantic development: Allen Leech revealed that he鈥檚 engaged to actress Jessica Blair Herman.

The bride and groom-to-be, who have been dating since 2016, took to Instagram to share the big news with fans. 鈥淗appy Valentine鈥檚 Day @jessicablairherman,鈥 Leech, AKA Downton鈥榮 Tom Branson, wrote alongside a photo with Herman. 鈥淔irst one as a fianc茅! Thank you for saying yes and for making me the happiest.鈥

He also clarified that he didn鈥檛 actually pop the question on Valentine鈥檚 Day, adding, 鈥(And no I didn鈥檛 do it today. It鈥檚 been a while.) xx鈥

The pic he posted shows the lovebirds posing against a scenic outdoor backdrop, with the actress鈥 hand on Leech鈥檚 chest so we get a clear view of her engagement ring. It appears to be a single center stone on a delicate band.

Herman, whom you might have seen on American Crime Story, Fresh Off the Boat, or Modern Family, also shared a photo on her own account, of Leech giving her a kiss on the temple. 鈥淭he day you proposed was one of the best days but every day with you is my favorite,鈥 she captioned the image. 鈥淚 love you! Happy Valentine鈥檚 Day @therealleech!鈥

Fans are thrilled by the news and have been leaving their well wishes in the comments of both posts.

We鈥檒l add ours, too: Congratulations to the happy couple!
