Lennon Gallagher kept it casual as he led the stars out and about at the Burberry Festival Pub Quiz in Notting Hill on Wednesday evening.
The son of Liam Gallagher and Patsy Kensit opted for a khaki plaid jacket which he paired with a simple black Burberry Tee.
He completed the look with a pair of dark blue oversized jeans, smart black shoes and large black sunglasses as he was seen puffing on a cigarette outside the venue.
Meanwhile Mia Regan embraced a more preppy look as she paired a stylish checked playsuit with a grey short-sleeved polo jumper.
Putting on a leggy display in the ensemble the model, 22, added a statement pair of dark green leather boots and black and white plaid handbag.
Sugababes star Keisha Buchanan also made sure to flash plenty of skin in a black mini dress as she strode down the street.
The singer, 40, covered up in a dark khaki Burberry coat with a plaid feature panel on one side.
She added a pair of tortoise brown framed sunglasses, beige leather ankle boots and a white leather handbag.
Keisha was joined by her fellow Sugababes Mutya Buena and Siobhán Donaghy after the threesome recently performed at Radio 1's Big Weekend last month.
Mutya, 40, put on a very busty display in a bralette top which she wore underneath a stylish cream trench coat.
The singer accessorised the look with a pair of gradient lens square shades, Burberry headband and black sandals.
Elsewhere Siobhán kept it more casual in a pair of light denim jeans, black T-shirt and famous Burberry trench coat.
Jordan Stephens opted for a summery ensemble in beige linen trousers and a plaid shirt which he wore open over a white T-shirt which read 'Love You'.
Nick Grimshaw also opted for a plaid shirt over a white T-shirt which he paired with straight legged denim jeans and shades.
It has been a busy week for Lennon after he attended day one of Royal Ascot on Tuesday.
The aspiring singer was joined by his girlfriend Isobel Richmond who opted for an elegant, pale pink slip dress tat featured floral detailing and ruffles across the shoulders.
Lennon wore a grey top hat, which he teamed with a tailored jacket and a beige waistcoat by Gieves & Hawkes.
As well as modelling, Lennon has also followed in his father's footsteps by making music with his band Automotion.
Last year Lennon - who has graced Italian Vogue and appeared at London Fashion Week - spoke candidly to MailOnline about the world of modelling and admitted it can be 'difficult at times'.
He was first scouted at the age of 16 while walking down Brick Lane and he explained: 'I was walking in Brick Lane, and I was like, 16.
'I just got an army jacket and I was walking away from the store, this woman pulled me over and was like, ''You should be a model, take this card. We have a shoot in Africa, you should do it''.'
Noting the situation seemed 'sketchy', Lennon went on: 'I didn't do the shoot because it seemed really sketchy, so I told my mum and she was like, ''If you want to get into it, I know some people''.'
Lennon told how he reaches out to his agent if ever he feels unsure about a shoot or casting call.
'It's always pretty difficult putting yourself up for castings and stuff and putting yourself out there,' he stated.
'And then there's like hundreds of people who maybe look a bit like you, look so different to you, and like everyone is going in and out, and you're like, ''I'm not going to get this!'''
Lennon admitted: 'You kind of do get a bit insecure, I can't lie,' before noting the importance of asking for help.
'For the context of being in the studio, if there's something you don't like you can always call your agent and they are always willing to help you out.
'They'll always try to help you out to their best ability. You're not alone.
'You should never feel like you should be pushed into something you don't want to do.'
