The Boyfriend hitmaker became linked to Lionel Richie's daughter in early August, 2016 and they enjoyed a jet-setting romance, with Sofia joining her man for a pair of concerts in Japan, before Justin treated her to a romantic Mexican getaway in honour of her 18th birthday. However, it seems the young couple's chemistry has since fizzled out, according to TMZ.com.

Sources claim Justin and Sofia haven't spent much time together since returning from their beach vacation in Cabo San Lucas, and have barely spoken.
They also haven't been spotted in public together for a few weeks, with Sofia attending a party with friends in Los Angeles over the weekend.
Justin and Sofia have yet to comment on the split report, which comes just days after the teen gushed about her "special relationship" with the singer.

During a candid chat with Billboard.com earlier this month, the model insisted she had faith their romance would go the distance, because Bieber is so unique.
"We have a special relationship," she smiled. "Justin is very easy to talk to, and that's hard to find with people in Los Angeles."
However, the stars' road to romance hasn't been easy - shortly after going public with their budding relationship, Justin blasted his own fans for attacking his new girlfriend after sharing snaps of the pair on Instagram.
His outburst even sparked a feud with his ex Selena Gomez, who criticised Justin for his behaviour, and he ended up making his account private after the rude comments continued to roll in.
