Keira Knightley has reportedly been trying to make her boyfriend Rupert Friend jealous by constantly gushing about her new co-star, Cillian Murphy.

Keira, who met Rupert on the set of their 2005 film Pride & Prejudice, is set to star opposite Cillian in new film The Best Time of Our Lives and has being talking him up to Rupert.

A source told the Daily Express: “Keira was blown away by Cillian’s performance on his latest film Sunshine, and kept going on about it to Rupert and about his beautiful face… She told him Cillian has the most amazing eyes and is an amazing actor.”

“There are a lot of passionate scenes between Keira and Cillian [in the new film] so there’s plenty of opportunity for Rupert to be hitting the wall if she carries on winding him up like this.”

“Keira is a tease and she loves to watch Rupert getting jealous. It’s all part of their relationship and they have these spats and then kiss and make up all over again.”
