Ian Somerhalder & Nina Dobrev
Nina Dobrev and Ian Somerhalder’s on-screen chemistry in The Vampire Diaries was so good that it wasn’t surprising that they dated in real life. However, when things ended between them, they continued to portray lovers on the show, which was allegedly when the rift started.
The feud also reportedly escalated once Somerhalder directed some episodes and began dating Twilight actress, Nikki Reed, soon after their breakup. However, Dobrev denounced the malicious rumors and said that she exited the show per the contract. As of 2021, Somerhalder is happily married to Reed.
