Unfortunately, 'Glee' star Lea Michele has been experiencing an emotional roller-coaster ride for quite some time now. While she enjoys the tremendous success of her musical-comedy television drama on FOX, she has had to cope with the loss of her boyfriend and former co-star Cory Monteith, who was just 31 when he met with a tragic fate due to an overdose of alcohol and drugs on July 13, 2013.

With 'Glee' Season 6 filming already underway, Michele's emotional feelings are becoming more intense because the series is coming to an end once and for all.

Michele, who portrays Rachel Berry on the show, tweeted on Nov. 16 saying, "Can't believe it's our last season! I'm going to miss these guys so much! #GleeSeason6 :("

Along with her tweet, Michele posted a few behind the scenes black-and-white photographs of herself along with co-stars Chord Overstreet (Sam), Amber Riley (Mercedes) and Kevin McHale (Artie). The snaps were taken at a photoshoot for the final season of 'Glee'.

Daily Mail reported that more recently, 'The Brunette Ambition' author got a supportive visit from her father Mark Sarfati on the Los Angeles set of 'Glee'.

The report further states that 56-year-old real estate agent Safarti, reportedly managed a delicatessen where his famous daughter worked sometimes as a child.

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

The other cast members of 'Glee' Season 6 include Naya Rivera, Matthew Morrison, Chord Overstreet, Dianna Agron, Jane Lynch and several others. The television series will return with Season 6 in early 2015.
