Lea Michele is in mourning. Following the shocking news that her boyfriend and Glee costar Cory Monteith died at the age of 31 on Saturday, July 13, the star is grappling privately with the loss.

The 26-year-old actress has not released a statement, but her rep tells Us Weekly in a statement, "We ask that everyone kindly respect Lea's privacy during this devastating time. Thank you."

Michele had stood by Monteith's side during his decision to enter rehab for substance addiction on March 31 of this year. "I love and support Cory and will stand by him through this," she in a statement at the time. "I am grateful and proud he made this decision."

The FOX star, who dated Monteith for a year, was recently enjoying a girls weekend at Las Ventanas in Cabo, Mexico, with her girlfriend, Jennifer Cohen. "Lea seemed very happy and relaxed," an insider told Us about her getaway, which she arrived home from on Monday, July 8. "It definitely seemed like a fun trip for her."

Foul play is not suspected and the coroner is investigating the cause of death.
