The Essex favourite was treated to a surprise birthday meal at Bodean's BBQ on Friday (15 May) attended by co-stars of past and present including Joey Essex, Dan Edgar and George Harrison.
Fran shared a picture of the group together to Instagram - how mega glam do Fran and George look?!
After dinner, the group continued the celebrations at Nu Bar in Loughton, Essex, where Diags and Fran were snapped holding hands as they headed into the venue.
We always knew Diags was a popular boy among the TOWIE cast so it's no surprise several co-stars took to Twitter to send him birthday love including James 'Arg' Argent who also included an old throwback picture! Love it!
Arg - who is off on a charity trek today - said: "Happy Bday @JamesBennewith Hope your having a great time & @Franparman spoils ya! Here's a old throwback for ya son x."
Other celebratory messages came from the likes of Chloe Sims and Charlie Sims.
Meanwhile, former TOWIE star Joey shared a video to Instagram showing the rather interesting way Diags' blew out the candle on his birthday cake... Take a look below!
Happy birthday to Diags!
Meanwhile, in other TOWIE news, we're getting just a tad excited - okay, ridiculously excited! - about the new series starting next month. It's been WAY too long since we saw the gang on our screens!
Once again, they'll kick off their summer series with a jaunt to holiday hotspot Marbs.
We can't wait!
