Julian Morris acknowledged a deeply personal milestone this week.
On Thursday, the actor celebrated his 18th anniversary with Landon Ross with a series of Instagram photos showing the couple on their travels together.
“18 years together, and they were the best ones because they were with you,” he wrote in the caption. “I love you @landonross.”
Ross, a visual artist based in Los Angeles, shared a similar series on his own Instagram account. “Beginning our 19th year is the best thing in life,” he wrote. “I love you.”
“This post made my heart explode,” wrote actor Keegan Allen, one of Morris’ “Pretty Little Liars” co-stars.
In an Instagram story posted Friday, Morris said he was “really moved by all the love and support” he’s received from friends and fans.
Morris, a London native, is best known for his portrayal of Dr. Wren Kingston on “Pretty Little Liars,” which ended in 2017 after seven seasons. His recent credits include episodes of “The Morning Show” and “The Good Fight.”
