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.
Jennie Garth and Peter Facinelli
Jennie Garth and Peter Facinelli have three kids together. Sadly, that was not enough to save their marriage.
Jennifer Aniston and Brad Pitt
We're saying of "all-time," right? Jennifer Aniston and Brad Pitt were together for seven years and married for four and consisdered Hollywood's golden couple when they got divorced.
Amy Poehler and Will Arnett
They were married for nine years. They have two kids together. And they starred on two of the funniest shows in TV history. How did this not work out?????
Jessica Simpson and Nick Lachey
This was before we knew that reality TV ruins all relationships. Lachey took Simpson's virginity, people! We figured this had to work out!
Susan Sarandon and Tim Robbins
They were together for 23 years when they announced their split in 2009. 23 years. That says it all, doesn't it?
Reese Witherspoon and Ryan Phillippe
Fans were devastated back when this marriage ended. They were then angry at Phillippe after it came out that he cheated on Witherspoon.
Vanessa Paradis and Johnny Depp
Amber Heard, who?!? Depp has two kids and was with Paradis for 14 years prior to their split.
Idina Menzel and Taye Diggs
Diggs even came out and acknowledged how sad people were by his split from the actress, which took place after 10 years of marriage.
Gwen Stefani and Gavin Rossdale
They were together for 19 years. They have three sons. And they split just days before their 13th wedding anniversary.
Arnold Schwarzenegger and Maria Shriver
This was more shocking for the WHY: Arnold fathered a child with the couple's maid!
Courteney Cox and David Arquette
They were married for 11 years and just seemed to cute and quirky as a couple. They remain good friends.
Justin Bieber and Selena Gomez
If they got back together now and broke up, we would not be shocked. But the first time it happened?!? So many tears were shed.
Rob Kardashian and Blac Chyna
They had a kid together and... okay, who are we kidding? Everyone saw this one coming.
Their marriage lasted for less than two years. We did not see this one coming!
Miley Cyrus and Liam Hemsworth
Their marriage only lasted eight months, but the two were together -- off and on, that is -- for like a decade!
