Gwyneth Paltrow's appearance on Glee was "a blessing" to the cast, Matthew Morrison has gushed.
The Oscar-winning actress joins the hit TV show as substitute teacher Holly Holliday, who launches a bid to steal Will Schuester's Glee Club job whilst he's off sick.
"It's amazing, she was such a blessing," Matthew, who plays Mr Schuester, revealed during a break from filming the show in Hollywood.
"It was so great because she's such a huge star and I feel like everyone here really tried to up their game because they really wanted to impress her, myself included!"
Matthew continued: "It was really great having her energy around and she's so talented - singing, dancing, acting, she can do it all!"
Amber Riley (Mercedes) and Jenna Ushkowitz (Tina) were blown away by how down-to-earth Gwyneth was.
"She's really fun and fitted right in. She was hard working, running the numbers every chance she got, just wonderful to us and very professional," Jenna revealed.
Amber added: "[Gwyneth] brought her children who are just the cutest little buttons. Nobody has ever come on here with diva attitudes and it's so refreshing because we're such big fans of all the guest stars on the show."
The second season also sees guest cameos from Britney Spears and John Stamos, but there's one star Matthew is desperate to include: "If I had a dream guest star it would be Harrison Ford! I don't think he sings but I've just grown up with the man and I love him," Matthew admitted.
:: Glee Season 2 begins on January 10 at 9pm on E4.
