Glee star Vanessa Lengies has promised that the winter finale next week will be a "rollercoaster".
The drama will take a seven-week break following its episode on February 21, Fox announced earlier this month.
Lengies, who plays Sugar, has now told TV Line that the final episode before the hiatus will contain some shocks.
"It's our regionals episode, and it's a huge jaw-dropper," she teased. "When I read the script, I was shocked, because it takes you on a big rollercoaster ride. In almost everyone's storyline there is a surprise, so I was on the edge of my seat the whole time I was reading it."
Lengies added: "It ends with one of those scenes where you just can't believe what's happening."
Lengies also dropped some hints about tonight's Valentine's Day episode of Glee, teasing: "Sugar is getting love from all angles in this week's episode.
"She's having boys fight over her, her daddy is throwing her a rager, her outfits are just getting better and better... All the cards are coming up Sugar, for sure!"
Glee is expected to pay tribute to Whitney Houston with a title card added to tonight's instalment following the singer's death at the weekend.
The show continues tonight (February 14) at 8/7c on Fox and will return to the UK on Sky1 on March 1.
