Twilight star Kristen Stewart is set to make a surprise cameo in her mum's directorial debut K-11.
The young actress was slated to give her mother Jules Mann-Stewart's film career a big boost by starring in the upcoming prison drama, but she was forced to bow out due to scheduling conflicts.
However, die-hard fans will be in for a treat when the movie is released later this year (12) - the 21 year old has taped a vocal cameo as a secretary named Karen.
Jules tells E! News, "Kristen has always been supportive of K-11. But you'll have to look very hard to find her. It's a micro-cameo. We'd already finished shooting the movie, but Kristen still wanted to be a part of it in some way."
Kristen won't be the only relative lending support to the project - the star's older brother Cameron is set to make his acting debut in K-11 as a jailed inmate named Sledgehammer.
