Lea Michele: Cory Monteith "will forever be in my heart"

Lea Michele has broken her silence following the death of her "Glee" co-star and real-life boyfriend Cory Monteith.

"Thank you all for helping me through this time with your enormous love and support. Cory will forever be in my heart," she wrote Monday on Twitter.

Michele included a photo of her and Monteith (shown above), smiling and embracing.

Monteith, 31, died on July 13 from a mixed drug toxicity involving heroin and alcohol.

A private memorial was held last week, where Michele and other members of the "Glee" cast and crew "shared memories and music in an emotional celebration" of the late actor's life.
