The Weekend - real name Abel Tesfaye has been linked to Angelina after they were spotted leaving celeb hangout Giorgio Baldi in Santa Monica just moments apart from one another last week.

While the pair are not known to be friends, there are some intriguing links between them, including the singer referencing Angelina's famous pout in one of his hit songs. 

Furthermore, The Weeknd's ex-girlfriend Selena Gomez once famously crossed paths with Angelina's ex-husband Brad, 57, back in 2016, while they were still married.

The National Enquirer had claimed that Brad 'shamelessly flirted' with Selena, 28, causing issues between him and Angelina, though the claims were denied.

The same year, The Weeknd released his hit song "Party Monster" that featured a reference to both Angelina and Selena, with the line: 'Angelina, lips like Angelina / Like Selena, a** shaped like Selena.' 

Then, in his 2016 hit single "Starboy" he referenced Brad singing: 'Let a n**** Brad Pitt, legend of the fall took the year like a bandit.'

Quirky: She flashed her toned midriff and wore a pair of wide leg jeans covered in glitter

Cute couple: The model, 24, and her art director boyfriend were seen taking a dip in the sea during their romantic holiday in Antibes just days after confirming their romance 

The Oscar-winning actress shares six children with ex-husband Brad; Maddox, 19, Pax, 17, Zahara, 16, Shiloh, 15 and 12-year-old twins Knox and Vivian.

Angelina filed for divorce in 2016 citing 'irreconcilable differences' and it was finalized in 2019. The former pair have been in a lengthy custody battle with the actress wanting sole custody and Brad fighting for joint.

Legal experts in Los Angeles told DailyMail.com in March that the pair have each spent over $1million in legal costs already - and said the custody battle could go on for six more years.
