Sienna Miller sure knows how to break up a family.

Well, sort of.

The British actress is now rumoured to be causing drama between on-screen siblings on ABC’s Brothers & Sisters.

According to an E! Online report, costars Balthazar Getty and Matthew Rhys are “no longer speaking because of the Getty-Miller romance.”

Rhys, who used to date Miller, recently learned of his costar’s new romance through the show’s producers.

A source told E! Online that producers were looking for Getty sometime this summer, and thought they could get a hold of him through Miller. They then asked Rhys if he could help them find Miller.

Big mistake–Rhys had no idea they were dating.

Getty’s rep, however, insists there is no bad blood between the two: “May make an interesting bit of more gossip but completely untrue.”

Reps for the show and Rhys did not comment.
