Angelina Jolie and Brad Pitt's daughter Shiloh, 18, shows off her dance moves after legally dropping dad's last name

Angelina Jolie and Brad Pitt's daughter Shiloh, 18, has got some slick dance moves.

On Saturday, her choreographer, Kolanie Marks, shared an Instagram video of his student busting a move to Capella Grey, Jaewon and Young M.A.'s track, Fly S**t.

In his caption, he praised the former couple's teenager and marveled over her 'growing' confidence. 

'Yo!! Thats it im officially her ADOPTED UNCLEA LMAO, the artistic director wrote under the footage. 'I've watched this so many times and the confidence is growing and building!'

He continued: 'Keep going @sh1lohj I'm so so proud.'

Marks also gave a shoutout to choreographer Devin Solomon.

He also shared a clip in his Instagram Story and wrote: 'She's getting so good! I'm happy that she's sticking to the training!' 

Last month, Marks revealed that he'd been training Shiloh for a few years and they met while she was taking a class at Millennium Dance Complex in Los Angeles. '

He said she has dedicated herself to trying to figure out' his style of dance and that is all they work on. 

They do not discuss her famous family, saying their relationship is 'very strictly based off of what we focus on, which is the dancing.'

'I totally forgot who she is in that moment, because that's not what we focus on when we're training,' he said. 'I wanted to give her praise, of just the hard work and dedication that she puts in.' 

Jolie and Pitt, also share Maddox, 23, Zahara, 19, Pax, 20, and twins Knox and Vivienne, 16. 

Earlier this week, it was revealed that Shiloh legally dropped her father's surname.

Shiloh, who hired and paid for her own lawyer when she filed to drop the Pitt name on her 18th birthday in May, filed to change her name from Shiloh Nouvel Jolie-Pitt to Shiloh Nouvel Jolie.

TMZ reported there was no formal hearing for the name change - with the petition granted on Monday, per official court documents.

Last month, Shiloh took out a newspaper ad marking the name change – which is a standard step before the court approves a name change.

The notice also stated anyone who had objections to the petition should show up in court.

A source close to the matter told Dailymail.com last month: ‘Shiloh hired her own lawyer and paid for it herself, so Angie doesn’t know and can’t speak for it.

'But, if you’re asking if this is connected to the abuse history or the violation of Shiloh’s victims rights, yes, that’s part of it.'
