The pair were seen arriving at the Staples Centre in LA on Wednesday evening – and although they chose to walk inside the venue separately, they waited for their VIP passes together, and were spotted leaving in the same black SUV at the end of the night.

Chloë Moretz and Brooklyn Beckham leaving the concert together
Brooklyn, 15, was smartly dressed for his evening out with the actress, wearing a blazer over a green T-shirt. Chloë, 17, chose a sweet white lace top and jeans.
Last week, Chloë was pictured hand-in hand with New York college student Julian Moraes – which seemed to put an end to reports that she was romantically involved with Brooklyn. But the concert has left fans wondering once again about her relationship with the Beckhams' eldest son.
Regardless, it's clear that the pair have become close. Brooklyn sweetly supported the star at the premiere of her latest film, If I Stay, last week, and they were seen together at the Teen Choice Awards on 10 August.
The couple have been rumoured to be dating for the past few months
Also attending the concert on Wednesday was Brooklyn's dad David Beckham. He posed for a picture backstage with Ed's support act, Rudimental, who were clearly excited to meet the football star.
David and Victoria Beckham are understandably protective of their son, and are often seen chaperoning him during his 'dates' with Chloë.
One onlooker, who saw Brooklyn and Chloë at SoulCycle recently, told People, "Brooklyn is always chaperoned by one of his parents. But both David and Victoria must be ok with Chloë because they will chat briefly with her and then leave them alone."

Chloë seemed to shed some light on her dating outlook in a recent interview with the Sunday Times magazine.
"I don't even know what dating is at this point," she said. "It's all so stupid. Why can't you just hang out with each other? Go to dinner if you want to? Why can't you go skateboarding if you want to go skateboarding with a guy?"
