Cory Monteith, who plays Finn on 'Glee,' is all done with his most recent trip to rehab.

PEOPLE reports that Monteith and his on-and-offscreen love, Lea Michele (who plays Rachel Berry on the series), reunited at the airport on Friday (April 26) when he returned. The duo were said to be "very happy, smiling the entire time," and when security guards asked Monteith how he was doing, he simply replied, "Good."

Monteith initially checked into rehab in March after falling back into some old bad habits. He tweeted to thank his fans and supporters upon his return home:

Michele also was thrilled to have her boyfriend home, writing:

Michele apparently is a good influence on Monteith, who previously battled substance abuse issues as a teen. A source said, "Lea is an excellent influence on him. She's good for him. She's really calmed him."

Congrats and best wishes to Monteith on his continued recovery!
