Lea Michele will mourn Cory Monteith privately on the anniversary of his death.

The 27-year-old actress was left devastated when her boyfriend and 'Glee' co-star died of a drugs overdose on July 13 last year, and though she will reportedly honour him in a small way on social media, she plans to spend most of the day alone.

A source told HollywoodLife.com: ''She is going to make a mention of it on Twitter and Instagram but for most of the day she is going to mourn on her own time and keep her thoughts and feelings to herself.''

Lea - who is now dating Matthew Paetz - is convinced Cory would have wanted her to move on and be happy so is trying her best to do that.

The source added: ''She knows that Cory would want to live her life and that is exactly what she will be doing.''

The brunette beauty is said to be incredibly happy with her new boyfriend and friends say they are well suited.

A source said recently: ''They make a good team. Lea's friends say he's a great guy and dotes on her. Lea's found some happiness again.''
