Nina heartbroken over ex-bf's link-up rumours with Emma Stone?

"The Vampire Diaries" star Nina Dobrev was reportedly heartbroken after she heard rumours that her ex-boyfriend and actress Emma Stone are dating.

The 27-year-old actress' heartbreak caused her to plan a return to "The Vampire Diaries" to hide the pain, reported Aceshowbiz.

Austin and Nina called it quits earlier this year after seven months of dating. They broke up apparently due to their conflicting schedules.
