They say that divorce is one of the most stressful things a person can go through, but sometimes a regular celebrity split can be just as drama-filled before anyone has even put a ring on it.
For every amicable breakup (or “conscious uncoupling” as Gwyneth Paltrow helpfully labelled it back in 2014), there’s an explosive split filled with finger-pointing, Twitter accusations and shade-throwing in every which direction.
Yes, it seems celebrities never forget the world is watching quite as badly as they do when they’re going through a split, and we’ve narrowed it all down to just 15 of the messiest showbiz break-ups ever...

Taylor isn't the only one of Calvin's exes he's got beef with, though. Rita Ora revealed shortly after their split that the DJ had forbidden her from performing their collaboration 'I Will Never Let You Down' at an awards ceremony in the US.
He later insisted he had a 'damn good reason' for putting the brakes on her scheduled performance.

It was drama from the beginning with these two, who met in the 'Celebrity Big Brother' house in January 2016, when Stephanie was still dating model Sam Reece.
Although they tried to make a go of it in the outside world, it wasn't long before infidelity accusations were thrown from both sides, with Stephanie eventually announcing she was pregnant with Jeremy's child, though he has insisted the baby is not his.
They were truly love's young dream in the early 2000s, but things quickly turned sour and they broke hearts all over the world when they announced they'd split.
He later addressed the break-up in his track 'Cry Me A River', and has repeatedly made digs at her over the past decade.

Kanye and Amber split in 2010, but it was years later that he took a swipe at her in the press, suggesting new wife Kim Kardashian had made him take "30 showers" before they got together, because of their relationship.
Amber then caused ripples on social media with #FingersInTheBooty-gate, with Kanye later using Amber as one of 12 celebs in his shocking 'Famous' music video.

It was one of the most outrageous 'Made In Chelsea' moments ever when one of our fave couples went their separate ways, after it was claimed Alex had been unfaithful.
While he initially owned up to one indiscretion, it later transpired that an entire orgy had taken place without his girlfriend's knowledge, and their relationship swiftly ended.
Rob was furious with Rita when they broke up, posting a string of crude tweets about her, including one where he accused her of 'cheating on him with 20 dudes'.

We're seeing a bit of a pattern here, but it was only long after their 'amicable' split that things appeared to turn sour for David McIntosh and Kelly Brook.

They haven't been together for years, but it seems these two still have a lot of unfinished business.

Things turned really sour between Naya Rivera and Big Sean once they'd ended their relationship, with the 'Glee' actress accusing her ex of stealing her Rolex, something he has vehemently denied since.

He later issued a public statement in a video, urging Chantelle to allow him to see their baby daughter, Dolly.

Kelly has never been one for holding back on social media (just ask Dannii Minogue, or her father's former mistress), and this was never more true than when she split with Luke Worrall.
After discovering he'd slept with a model behind her back, Kelly blasted her then-fiancé on social media, calling him the 'biggest piece of shit ever' also accusing him of sleeping with 'hundreds of girls as well as men behind her back'.
