We find it very difficult to talk about the following celebrity break-ups.
We're still in shock that they happened. We're still wishing the stars at the center of them give it another go with one another. But we're not hopeful.
Here is a rundown of the splits that took us most aback when they went down...
Ian Somerhalder and Nina Dobrev
Did you ever see these two back when they were dating and promoting The Vampire Diaries together? It was like they were the only people in the room. We still can't believe Ian married someone else.
Demi Lovato and Wilmer Valderrama
They were together for six years! They packed on the PDA on social media! They talked marriage mere weeks before their demise. We remain stunned.
Taylor Swift and Calvin Harris
They made it work for 15 months. That's a very long time for Swift. We really thought she had found The One.
Robert Pattinson and Kristen Stewart
The most shocking cheating scandal in Hollywood history? Maybe, right? Stewart put the stunning nail in the coffin of this relationship when she made out with director Rupert Sanders.
Jon Hamm and Jennifer Westfeldt
They never married. But they were together for 18 years and they barely made any gossip pages during that time.
Kim Kardashian and Reggie Bush
It's easy to forget now, what with the whole Kanye thing, but Kim and Reggie seemed totally in love back in the day. He seemed like the perfect man for the sex tape star.
