Kristen Stewart has reportedly set her sights on Sean Penn to make Robert Pattinson jealous.
The Twilight stars split up earlier this year after failing to move on from Kristen's infidelity with married director Rupert Sanders in 2012.
Robert was recently linked to Sean's daughter Dylan after the pair were spotted getting cosy at The Viper Room club in Los Angeles.
In what is thought to be a bid to keep her eye on her ex-boyfriend Kristen is reportedly keen to make a move on 53-year-old Sean, who directed her in 2007 film Into The Wild.
She is said to have arranged a dinner date when she returns from filming in Switzerland.
"Kristen finds Sean attractive, but her friends believe arranging dinner with him could simply be a plot to get Rob's attention," an insider told British magazine Closer.
"She wants to make Rob jealous and get back at him, especially as Sean's a proper star and Dylan isn't. Being close to Sean will also mean she can keep tabs on Robert and his romance with Dylan."
Robert is said to be smitten with Dylan and was shocked to hear his former flame is trying to stay in the picture by spending time with Sean.
However he and Dylan have allegedly agreed to not let the stress get to them and look at it as a casual thing.
Sean split from his wife Robin Wright in 2010 and has since dated younger women including Scarlett Johansson, 28.
"Rob's really into Dylan - he insists the other girls he's been linked to are just friends. Dylan heard from her dad that he'd arranged to meet up with Kristen and she told Rob straight away," the insider added. "He was a bit taken aback, but Dylan has just dismissed it as another of his father's flings with a young actress. They both agree it's an awkward situation!"
