It's been an emotional roller-coaster for "Glee" star Lea Michele, who has experienced some of the highest highs with her success on the show as well as the loss of her beloved co-star and boyfriend Cory Monteith, who died from an accidental drug and alcohol overdose at age 31 in July 2013.

Now with "Glee" Season 6 underway, Michele is feeling more emotions as the Fox series is quickly coming to an end.

On, Nov. 16 the "Glee" star, who plays Rachel Berry, tweeted: "Can't believe it's our last season! I'm going to miss these guys so much! #GleeSeason6 :("

Michele included a couple of behind the scenes, black-and-white snapshots of herself with co-stars Chord Overstreet (Sam), Amber Riley (Mercedes) and Kevin McHale (Artie) at a photoshoot for the final season.

On Monday, "The Brunette Ambition" author got a supportive visit from her father Mark Sarfati on the Los Angeles set of "Glee," according to the U.K.'s Daily Mail.

Safarti, a 56-year-old real estate agent, also reportedly used to run a delicatessen where his famous daughter occasionally worked during her childhood.

"Back in July, Michele teased a snap implying Rachel will be covering 'Frozen's' hit song 'Let It Go' in season six," the Daily Mail adds. "The Oscar-winning anthem was originally performed by the Broadway belter who played Rachel's birth mother, Idina Menzel."

"Glee" Season 6, which also stars Naya Rivera, Dianna Agron, Matthew Morrison, Jane Lynch and Chord Overstreet, among others, will debut in early 2015.
