The small screen starlet tells People that she will stand by her man as he undergoes treatment for substance abuse.

"I love and support Cory and will stand by him through this," she tells the mag. Adding, "I am grateful and proud he made this decision."

Lea is also thankful for the love their fans have been sending the couples' way, tweeting "Thank you all so much for all your love, support, and encouragement. It's means the world to us..," on Monday.

This isn't the first time the actor has sought help for alcohol and drug addictions, Monteith had a short stint in rehab when he was 19.

Lea, 26, and Cory, 30, went public with their relationship last April.

Cory also has the support of "Glee" creator Ryan Murphy who tweeted, "I am so proud of Cory Monteith and love and support him 100%," on Monday.
