Glee star Dianna Agron's mother called the actress in tears after watching her character's car crash in the last episode of the series - because it seemed so real.

Agron's drama queen character Quinn Fabray was racing to get to ex-boyfriend Finn's wedding while texting and driving when her vehicle was sideswiped by a truck. The episode went black upon the impact of the crash - and Agron's phone started ringing immediately.

She tells TV Guide magazine, "She (mother) said it seemed so real. She told me, 'I feel like you're dead and I haven't said my last words.'"

And Agron confesses she had to let her mom know what becomes of her character: "I couldn't make her wait - she's my mom!"

Fans of the show will discover whether Fabray lives or dies when Glee returns to American TV screens next week.
