The couple donned their best fancy dress outfits for the bash, which took place at a fairground in Kent on Sunday afternoon (27 July).
Danielle, who channeled Sandy Olsson's finest Rydell High cheerleader outfit, couldn't stop smiling as she walked with the poms poms in her hand, while James draped his arms around her.
Just look at how blissfully happy they seem!
Reality stars James and Danielle, who rekindled their romance during the show's current series, jumped on a number of rides including the Ferris wheel and merry-go-round.
James, who was channeling Danny Zuko with his all-black outfit, couldn't keep his hands off his girl, as he showered Danielle with kisses throughout the day.
In last night's episode, at the launch party of Danielle's new boutique DANNI, James said: "About five weeks ago, I wouldn't have even been here. It's mad how far we've come in five weeks. I'm proud of you."
Last week, James proved just how proud he was, as he joined Danielle at her shop launch in Hornchurch, Essex.
TOWIE continues on Wednesday (30 July) at 10pm on ITV2.
