2016 forges bravely ahead with further proof that love is fleeting and heartbreak is endless, especially when it comes to celebrity couples: Justin Bieber and his girlfriend of one month, Sofia Richie, have reportedly broken up, according to TMZ.

Sources tell the publication Bieber and Richie — who have been photographed together several times since their rumored romance reportedly began earlier this summer — were never involved in a serious relationship to begin with, and things between the couple simply fizzled out with time.

Despite claims that things were casual between the two, Bieber and Richie did fly to Japan together -- where Bieber performed as part of his Purpose World Tour -- back in August, and have documented their hangouts ad nauseam on social media, as young couples often do. The former pair also traveled to Mexico together late last month to celebrate Richie’s 18th birthday in Cabo, according to US Weekly.

The breakup comes a little over a month after 22-year-old Bieber famously deleted his Instagram account due to fans' increasingly negative comments about Richie, and their refusal to heed his warnings.

“I’m gonna make my Instagram private if you guys don’t stop the hate,” he told fans via photo caption. “This is getting out of hand. If you guys are really fans you wouldn’t be so mean to people that I like.”
