It’s been four years since Lea Michele said goodbye to Cory Monteith, but her love for him lives on.
In memory of her late ex-boyfriend and Glee costar, Michele posted a throwback, black-and-white photo of the former couple from happier times on Twitter Thursday.
“Hard to believe it’s been 4 years…” Michele, 30, captioned the photo, shared on the four-year anniversary of his death.
“We miss you C… love you more,” she added with a solo red heart emoji.
Monteith passed away at the age of 31 on July 13, 2013; his body was found in a Vancouver, Canada, hotel room. According to authorities, he died of a “mixed drug toxicity” of heroin and alcohol.
The Canadian native completed a month-long stint in a treatment facility for substance addiction in April 2013 and had been open about his lifelong struggles with substance abuse.
Michele was 26 at the time of Monteith’s passing, and dated the actor for more than a year.
Although the pair hadn’t been photographed together in the recent days leading up to his death, a source close to the actress told WHO at the time, “They were happy and very in love.”
“I love working with Cory, I always have,” Michele told WHO in September 2012. “He really, really inspires me, and he motivates me and I think he’s just so talented. Working with him has been one of the best experiences of this whole process.”
