The actress admits she's a big fan of the programme and, by getting her cousin Elise, on the set, she hopes to get some behind the scenes access and gossip.
Dunst says, "I did her bio (biography) for her... and she's really cute... I think they'll totally pick her, but we haven't done the video yet.
"We want her to be one of the girls... She'd just be laughing at the rose ceremony (where girls are rejected)."
And the actress admits her cousin's involvement would make the season extra special: "It's ridiculous, but it's just like some of the best television - the fact that everyone's so concerned about this rose.
"And they don't eat and they're all wasted (drunk)... and then they're, like, sobbing to each other about this man they've just met."
