Fox' hit series Glee is gearing towards its series finale, which is titled, Dreams Come True, and will air on 20 March, 2015.

Glee has officially wrapped production and Matthew Morrison and Kevin McHale have revealed a few details about the show's series finale.

Morrison, who has now played Will Schuester through six seasons of Glee, revealed to E! Online that they were done filming for the show this Saturday (22 February).

"We just wrapped about an hour ago," Morrison told the website. "It was a tough day. I'm not going to cry now because I kind of got it all out, but it was a really tough day."

The report adds that Morrison will be singing the very last song in the final scene of the series finale.

"It was a beautiful send-off," Morrison said, of the final song. "But it was tough. I was singing to all the kids and Amber Riley starts crying and I'm like, 'Come on, don't do this to me right now.' And then Lea Michele starts crying and then Darren Criss and Chris Colfer."

As is to be expected, there have been a lot of tears shed as the series comes to an end this year.

"There were a lot of hugs and a lot of tears," he said. "It's been an amazing almost seven years."

There is no word on what the final song in the series finale will be, but there are rumours that the Glee team might be reprising Journey's Don't Stop Believin', the song that turned the Fox show into the hit it would become in the very first episode back in 2009.

Another Glee star Kevin McHale also dished about the series finale of the musical show, adding that late costar Cory Monteith will be acknowledged.

McHale, who plays Artie on the series, spoke with AccessHollywood Live this week about the Glee series finale.

"I'm satisfied. I was reading it and the last two episodes are airing back-to-back, so it's kinda this double whammy all at the end," he said.

"I think [viewers will] be happy. I was happy. They tie up a lot of great storylines and you get to see these people in a new light and follow their journey. These characters have gone through a lot and I think there's a good payoff at the end."

The actor also talked about how the show would honour Monteith, who played star quarterback Finn Hudson in the series and who died unexpectedly in 2013.

"I think [Finn] is always remembered and especially at a time like this at the very end, there will definitely be some sort of mention of him," McHale revealed. "He'll be involved in some way."

He said that ultimately he and the entire cast will be "a mess" when the finale airs, especially his co-star Lea Michele, who plays Rachel.

"I would think maybe Lea [Michele will cry the most]... She can just turn it on. But, even in scenes when I look at her and she starts tearing up, it gets me. There's something about when she cries. It hits you."

Meanwhile, Lea Michele also shared a group photo of everyone on the final day on set.
