On Thursday (2nd December), the London-born actor shared a heartwarming post on Instagram, in which he wrote: “18 years together, and they were the best ones because they were with you.
I love you.” Morris’ post includes pictures and videos from throughout their relationship, which started when Morris was only 20 years old.
Various stars congratulated Morris and Ross on their anniversary, such as Brant Daugherty, Finn Jones, Nyle DiMarco, Charlie Carver, Jojo, Tyler Blackburn and Lucy Hale. “The hotness though,” said Hale, his former Pretty Little Liars co-star. “Congrats you two.” He had previously shared posts with Ross, but their romance had never been confirmed.
