Lea Michele's seemingly perfect relationship with boyfriend and late "Glee" co-star Cory Monteith is touched upon in the upcoming issue of "Marie Claire" Mexico. 

The magazine's editor-in-chief Ariadne Grant is sharing with readers the details of Lea's photo shoot, which took place in Los Angeles on June 7th, just five weeks before Cory's death on July 13th. 

According to "E! News," Grant says Cory visited the set that day and was "in great spirits" and "very nice to everybody there."  The editor adds that he and Lea were "obviously happy and in love" and that the actress lit up when he showed up to support her.  

Lea spoke about Cory for the cover story, calling him "the best person" she knows.  She also said she was "so thankful for him." 

Since his death, Lea's reps have released a statement saying she's "deeply grateful" for the support of her family, friends and fans.
