Cory Monteith's Glee Co-stars Tweet Support

Ryan Murphy is ''proud'' of Cory Monteith for checking himself into rehab.

The 30-year-old actor - who plays Finn Hudson in the comedy musical - recently voluntarily admitted himself to a treatment facility for substance addiction and creator Ryan is impressed with Cory's brave decision.

He tweeted: ''I am so proud of Cory Monteith and love and support him 100 percent.''

Cory's co-stars also added their support with Kevin McHale writing ''Love you, Cory. So proud of you,'' and Jenna Ushkowitz tweeting: ''Sending lots of love and light to Cory. We love you.''

Chris Colfer tweeted, ''Anyone who helps themselves is a hero in my book.''

Meanwhile Dot Marie Jones called Cory ''the sweetest man'' and warned people not to judge others.

She wrote: ''We are - and always will be - here for you. I love you always. Stay strong. You never know what someone is dealing with in their personal life. Don't pass judgement.''

After Cory's admission to rehab was announced, his co-star and girlfriend Lea Michele issued a statement declaring her intention to stand by him.

She said: ''I love and support Cory and will stand by him through this. I am grateful and proud he made this decision.''

Lea later tweeted: ''Thank you all so much for all your love, support, and encouragement. It's means the world to us..''
