Cruz Beckham's girlfriend Jackie Apostel is "in awe" of Victoria Beckham

In an Instagram post after the event, she wrote: "@victoriabeckham, we are all so in awe of you.

"To me, it's the little things such as the fact that you wake up every morning, positive and ready to be a bright light to everyone around you that might need it, no matter what is going on with yourself.

"You want every single person you love to succeed and do their best and will do anything you can to help them, and gladly.

"On top of the unbelievably smart business woman that no doubt you are, that is definitely what impresses me the most every day. your resilience and drive is inspiring.

"glad everyone gets to see a little glimpse of the hard working, intelligent and hilarious person you are in this doc. we love u! (sic)"

Meanwhile, David and Victoria's eldest son, Brooklyn Beckham, 26, is believed to be estranged from the rest of the family.

She recently opened up about how she and her husband are "really close to the kids", but failed to mention their eldest.

She told the Sunday Times Culture magazine: "Harper's still 14, so she's living at home. So is Cruz, who is 20. I see both of them every day.

"Romeo doesn't live at home, so I see a little less of him."

Brooklyn - who wasn't present at the premiere this week - recently claimed he "never" worries about gossip as he praised his wife Nicola Peltz.

He recently told the Daily Mail newspaper: "There's always going to be people saying negative things but I have a very supportive wife.

"Me and her, we just do our thing, we just keep our heads down and work. And we're happy.

"Everyone is always going to say rubbish. I just try and do this, play some golf with some friends. It's good fun."
