While some relationships grew even stronger after spending 24 hours a day, seven days a week together, plenty of other celebrity romances imploded.
As Julianne Hough and Brooks Laich become the latest A-list casualties of love lost in lockdown, we look back at the couples who couldn’t overcome all that time spent together.
Julianne Hough and Brooks Laich
The US Dancing With The Stars alumna filed for divorce from her Canadian former-NHL player husband on November 3, six months after they announced their separation on May 29.
Suspicions were raised when Hough began quarantining separately from her husband of three years in March – she in California and him in Idaho.
Demi Lovato and Max Ehrich
The romance that went from zero to 60 in under 0.3 seconds fizzled out just as fast as it heated up in September. The relationship between the singer and the Under The Dome actor began in May, and he soon popped the question with a $1 million diamond ring in June.
However in the space of a few months, Lovato went from, “I knew I loved you from the moment I met you” to “quarantine either makes or breaks the deal.”
Armie Hammer and Elizabeth Chambers
The Rebecca actor and his bakery entrepreneur wife called it quits in July after 10 years of marriage. Having quarantined in the Cayman Islands together, along with their two children, the moment lockdown finished, Hammer jetted back to the US alone.
"I don't think I handled it very well," he told GQ. "I think, to be frank, I came very close to completely losing my mind."
Cardi B and Offset
Nearly three years after Cardi and Offset wed, the mum-of-one filed for divorce on September 15. However, according to Page Six, Cardi B has had yet another change of heart and petitioned to dismiss her divorce on Monday, November 2.
"You know how I be arguing with y'all on social media? That's exactly how we are, between me and my man," the WAP rapper told her Instagram followers in October.
Kelly Clarkson and Brandon Blackstock
Singer-turned-talk show host, Clarkson filed for divorce from her husband in June, after almost seven years together. The pair had been quarantining in Montana with their two children, River Rose, 6, and Remington, 4, before Clarkson filed in LA.
She’s been working on new music that she says will address the split.
Sofia Richie and Scott Disick
Breaking up in May after almost three years together, the model and the reality TV star split after Disick’s most recent stint in rehab where he sought treatment for “past traumas”.
Scott, who has three children with his ex Kourtney Kardashian, is said to have moved back in with her to continue quarantining with them.
Lili Reinhart and Cole Sprouse
The Riverdale co-stars called it quits in March at the start of lockdown, their second split and this time their final one.
"What an incredible experience I had," the former Disney star wrote on his Instagram. "I wish her nothing but the utmost love and happiness." Following the break-up, Sprouse opted to quarantine with his Riverdale co-star, KJ Apa, who plays Archie in the hit show.
Megan Fox and Brian Austin Green
After a very public split and reconciliation back in 2015, the couple, who share three sons, confirmed in May that their marriage was over for good. While Fox moved onto a new romance with actor and singer, Machine Gun Kelly, Green insisted, “I will always love her, and I know she will always love me.”
However, the pair recently had an Instagram fall-out after Green posted a photo of their son, Journey, prompting Fox to comment: "I know you love your kids. But I don't know why you can't stop using them to posture via social media."
Miley Cyrus and Cody Simpson
Following her split from her actor husband Liam Hemsworth, Cyrus began dating another Australian, this time singer, Cody Simpson.
However, the couple called it quits in August with Cyrus saying of her next relationship: “I’m super into clean eating. I mean, people taking care of themselves. I knew that the place to meet my next partner was not going to be at Burger King.”
Taraji P Henson and Kelvin Hayden
Hidden Figures actress Henson had previously postponed her summer wedding to former NFL player Kelvin Hayden back in April.
But the star revealed in October that the postponement had become a cancellation, and that after two years together, they had called it quits.
Olivier Sarkozy and Mary-Kate Olsen
The businessman half-brother of former French president Nicolas Sarkozy and his actress-turned-designer wife, Olsen split dramatically back in May. Olsen lodged an emergency divorce petition in New York, which stated: “This is… an emergency because my husband expects me to move out of our home… in the middle of New York City being on pause due to Covid-19.”
However, the plea was rejected as an “emergency” due to the pandemic and she re-filed after restrictions were lifted.
Jay Cutler and Kristin Cavallari
The couple was holidaying in the Bahamas when the first lockdown came into force. But when the family returned to Nashville, The Hills star filed for divorce from her former NFL quarterback husband of seven years, announcing it on Instagram in April.
Although she called the split a “loving conclusion”, things soon went south, with the mum-of-three claiming in her petition that “he attempted to intimidate” her into a parenting plan she did not agree to.
