"Robsten", "Jariana" and "Jelena" were considered to be the power couples of 2012 not until these couples called it quits this year. Of course, they have been replaced by other power couples by the name of "Nolivia", "Zerrie" and "Jamily." Check out all the youngest and newest Hollywood power couples of 2013.

First up are "The Mortal Instruments" stars, Lily Collins and Jamie Campbell Bower aka "Jamily." These two started dating in 2012 during the filming of "City of Bones" but had allegedly called it quits August of this year. Obviously, no one believes the two have split judging from their PDA during interviews and red carpet premieres. They've even been named the next "Robsten" couple given their uncanny resemblance to Robert Pattinson's and Kristen Stewart's past relationship.

Next are Nick Jonas and his "Miss Universe" gal, Olivia Culpo aka "Nolivia." The pair started dating this year but apparently things have gotten serious between them. Last August, Nick flew all the way to Rhode Island to meet Olivia's parents. The verdict? Culpo's parents love Nick and believe their daughter has great taste in men.

One Direction's Zayn Malik shocked fans this year with his engagement to Little Mix's' Perrie Edwards. The pair has dated for quite a while and has stuck together despite the countless cheating scandals involving Zayn. Taking cue from Beyoncé, Zayn put a ring on it. The "Zerrie" couple is scheduled to tie the knot as soon as the 1D tours end.

Zayn Malik isn't the only One Direction cutie that has been in a serious relationship for long. Louis Tomlinson and Eleanor Calder are considerably the strongest couple having faced Twitter hate and gay rumours. "Elounor" as they are called have been dating for almost two years.
