The Only Way Is Essex narrator Denise van Outen will appear on the show for the first time as it celebrates 10 years on the air tomorrow night.

The Basildon native has provided the voiceover for the ITVBe reality series since its first episode in 2010 and has previously spoken of her desire to appear on the show itself.

Although she will not feature in scenes with other cast members, Van Outen will be shown in vision from her home, introducing a special nostalgic episode to mark the milestone birthday.

Several former stars will make guest appearances in the episode, including Mario Falcone, who returns to Essex with his young son for a catch-up with the Sims siblings.

The special 75-minute episode airs Sunday, October 11 at 9pm on ITVBe.
