Eliza Spencer Diana

The summer is ending on a high for Princess Diana’s niece, Eliza Spencer. The 33-year-old model and socialite is engaged to her longtime boyfriend Channing Millerd. The pair announced their engagement in a sweet Instagram post simply captioned, “Forever and Ever.” The couple began dating in February 2016. They’ve often shared romantic posts, and many wondered when Channing would pop the question. Her twin sister, Amelia Spencer, married her longtime love, Greg Mallett, in 2023. The sisters love to do things together, so fans hoped it wouldn’t be too long before Eliza Spencer had her own grand wedding.

Well, it’s official, let the planning begin.
