"Vampire Diaries" is one of the teen-series that is loved by many people, either teens or adults...worldwide phenomenon as what they call it! "Vampire Diaries" is able to introduce three of the famous stars in the industry of supernatural TV.  Moreover, 2014 is also the year where they have biggest guest stars.

• Joseph Morgan as Klaus Mikaelson. I guess you've heard him already especially if you watch "Vampire Diaries" regularly. He's there on the spinoff of "The Originals" so how could CW afford not to show his face in the show? By the way, Joseph Morgan played the role of Klaus Mikaelson who was the immortal hybrid.
• Daniel Gillies as Elijah Mikaelson, brother of Klaus Mikaelson. Elijah was also one of "The Originals" stars together with his brother Klaus. However, he was first introduced as regular guest star of the series. You'll know him because he is known for his Shakespear's wit and dapper suit.
• Claire Holt as Rebekah Mikaelson, the sexy sister of Mikaelson's brothers. Just like his onscreen brother, Rebekah's character also started as guest star.
• Cassidy Freeman as Sage. Although Freeman wasn't able to play as original vampire with her own spinoff show, yet she was that fierce also. For those who are no familiar with, she was the one who played the role of an old school vampire. She was the vampire whom Finn was interested with.
• Arielle Kebbel as Lexi Branson. While there are fans who would rather argue about Delena and Stelena still it cannot be denied that the entire TVD fandom are into Lexi Branson. Either undead or even afterlife, Lexi is still the bestie to Stefan.

Aside from these top five best guest stars of "Vampire Dairies" there are also great stars who has been part of the series like Kol Mikaelson played by Nathaniel Buzolic; Nina Dobrev played by Katherine Pierce; Mikael Mikaelson played by Sebastian Roché; Malachai "Kai" Parker played by Chris Wood; and of course Rose played by Lauren Cohan.
