The couple made the most of the warm weather on Sunday afternoon (14 July) by venturing away from their Essex hometown to attend the Barclaycard British Summer Time Concert in the capital, where they were treated to performances from the likes of Jennifer Lopez and Lionel Richie.
Both Charlie and Ferne (who seem to be the only couple that made it through series 9 of TOWIE without splitting up!) ditched the high maintenance style and over the top glamour that their Essex co-stars are known for, in favour of low-key looks that were perfect for their day at the park.
Charlie (brother of TOWIE regular, Chloe Sims) opted for navy blue shorts with a white short sleeved shirt and trainers, while his longtime girlfriend sported a simple black maxi dress and a quilted handbag.
We also love how Ferne has chosen to bring back a childhood favourite and put on a pair of glittery jelly shoes!
The twosome weren't the only stars from the popular ITV2 show at the concert however, as they were also joined by Big Mark and Carol Wright, who were no doubt enjoying each other's company even more after renewing their wedding vows earlier this month.
It's nice to see these TOWIE couples going strong!
