Cory Monteith seems to be doing well since completing a voluntary one-month stint in rehab, but things are obviously a lot different outside the closed walls of the center's safe haven. So his girlfriend and Glee co-star Lea Michele is doing anything it takes to make sure he doesn't spiral downward again.

Since filming is already complete for Glee's fourth season, the couple went on a little getaway, heading down to Puerto Vallarta, Mexico for a romantic vacation, where they were spotted eating lunch amidst palm trees.

Most importantly, Cory seemed relaxed and content alongside his ladylove.

It looks like the couple is super serious about making sure this time is dedicated to recovery, too. "Sailing off on another adventure..." Lea tweeted Saturday. "Putting down the electronics for the next few days.. Gonna rest up mind body and soul! See u soon!"

Before their trip to Mexico, Lea and Cory were spotted hanging out in Canada, where they indulged in some more R&R and also attended a Vancouver Canucks hockey game.

Cory, 30, checked into rehab at the end of March for substance addiction, the same problem that landed him there back when he was 19. Considering Cory is older, more mature, and clearly has a great support system behind him, he should be able to stay away for good after this latest stint!

Do you think Cory and Lea will last as a couple?
