All good things must come to an end and that includes even the sweetest celebrity couples. Taylor Swift and Calvin Harris appeared to be a match made in Hollyweird heaven throughout their one-year romance, but things quickly took a turn for the worst following their breakup in May.

While the pair took the high road announcing the end of their relationship — the DJ, whose real name is Adam Wiles, tweeting he only has “love and respect” for the “Shake It Off” singer — recent events have left TSwifties nothing short of shocked and confused. After Swift’s rep confirmed she played a part in creating his latest hit “This Is What You Came For,” Harris fired back on Twitter the same day, accusing Swift of trying to tear him down “for something to do.”

Calvin and Swift’s split is arguably one of the most gruesome in recent months, but it’s far from the only heartbreaking celebrity breakup this year. Relive some of the most horrendous 2016 splits in Hollywood below:

Iggy Azalea and Nick Young

Iggy Azalea and Nick Young made their plans to walk down the aisle public so when Young was caught on video admitting to sleeping with other women in March, everything understandably hit the fan. While Azalea initially forgave her basketball player beau, she announced in June that they had officially called off their engagement.

“I broke up with Nick because I found he had brought other women into our home while I was away and caught them on the security footage,” the rapper tweeted to her fans. Around the same time Young’s ex, Keonna Green, announced she was expecting her second child with the athlete. Azalea said she learned of the pregnancy through the press. 

Amber Heard and Johnny Depp

Depp’s promotion for “Alice Through the Looking Glass” in May was overshadowed by Heard’s decision to file for divorce days after his mother’s death and her claims he was abusive during their marriage. After Depp’s rep said the actor was hopeful “the dissolution of this short marriage will be resolved quickly,” Heard responded by submitting photos of her alleged injuries from Depp to the court and was granted a restraining order. 

Following speculation Heard was merely after her beau’s money, the actress rescinded her request for spousal support in June. The former couple’s day in court regarding the restraining order was postponed last month with the case expected to continue later this summer.

Kailyn Lowry and Javi Marroquin

“Teen Mom 2” fans had to say goodbye to one of their favorite couples in Season 7 of the MTV series. After Kailyn told her beau of three years she wanted to focus on her career instead of having another child, he told her it was a deal breaker. The military man backtracked his statement several weeks later on the reunion show, saying he didn’t want to part ways. Rumors about an upcoming custody battle over their son Lincoln and Kailyn’s son Isaac from a previous relationship have since emerged. The couple’s relationship remains up in the air as neither have filed official divorce documents.

Erica Mena and Bow Wow

Bow Wow and Erica Mena’s latest breakup occurred in late 2015 but the fireworks didn’t start until this calendar year. In June, Mena revealed on Instagram that the reason she and her fiancé broke up was because of his baby momma, Joie Chavis. Mena accused Chavis, who shares a daughter with the rapper/actor, of “stalking” and being jealous. She also said Chavis would text Bow Wow, also known as Shad Gregory Moss, late at night “begging” him to leave her.

Moss previously admitted Chavis played a role in the split, saying he didn’t like to see his fiancée feuding with the mother of his child. Moss also said Mena’s decision to post about her miscarriage on social media rubbed him the wrong way, resulting in their breakup. “I’m private with certain things,” he explained. “I just didn’t like that out there, I didn’t want that news out there.”

Sharon and Ozzy Osbourne

When it was reported in May that Ozzy and Sharon Osbourne had decided to split after over 30 years of marriage, cheating rumors immediately came into play. Sharon shortly after appeared on the CBS series “The Talk,” confirming rumors she kicked her musical beau out of their home but said she wasn’t sure if she would follow through with a divorce. It was later revealed that Ozzy allegedly had an affair with hairstylist Michelle Pugh. One of the couple’s offspring, Kelly Osbourne, responded to the drama by tweeting Pugh’s cell number to her fans in retaliation. 

Kaley Cuoco and Ryan Sweeting

“The Big Bang Theory” star Kaley Cuoco announced her separation from husband Ryan Sweeting in 2015, but it took several months for their divorce to become official. After reports surfaced the two were “miserable” together, they mutually decided to part ways. Court documents revealed Cuoco had to pony up $165,000 to the tennis professional, but was not required to pay spousal support. Cuoco also retained their two homes in California.
