R-Pattz was allegedly so annoyed that Stewart went out with the Tron Legacy star, that the pair had a fight and went through a period of not speaking to each other.

The source explained: "Kristen didn't mean anything by it. Garrett is her friend and he happened to be around, She was apologetic to Rob, but that didn't satisfy his jealousy,"

"After the hang up, Rob called on some friends and went out hitting the pubs in London. Kristen tried to call Rob on his cell but he wouldn't pick up."

Garrett, who stars alongside Jeff Bridges and Olivia Wilde in Tron, recently commented on his "blossoming friendship" with K-Stew, telling Marie Claire that the 20-year old actress was "incredible", while also praising her "devotion" to her job.

Following these reports, R-Pattz and K-Stew must have kissed and made up after they were spotted celebrating New Year's Eve together on the Isle of Wight.
