Lea Michele has posted a tribute to late boyfriend Cory Monteith on his birthday yesterday.

The Glee star described the actor, who died in July last year of a heroin overdose, as having "the biggest heart and most beautiful smile".

Fans showed their support for Lea, with one writing: "This photo broke my heart. i miss him so much. Stay strong love i love you. Happy birthday angel Cory. (sic)"

Monteith was found dead in his Vancouver hotel room just months after checking himself into rehab for substance abuse.

A friend close to the star claimed he was "healthy and in great spirits" just two days before he passed away.

27-year-old Lea spoke about her boyfriend's death at the Teen Choice Awards, saying: "He was very special to me and also to the world. And we were lucky to witness his incredible talent, handsome smile and his beautiful, beautiful heart. So whether you knew him personally or just as Finn Hudson, Cory reached out and became a part of all of our hearts - and that's where he'll stay forever."
