The Radio 1 DJ arrived at the Riverside Studios in London on Wednesday (28 August) looking chic and stylish in a green and blue patterned jumpsuit.
It was her first time back at work as a Juice team leader following the birth of her son in February.
Fearne was clearly thrilled to be back at work, tweeting after the taping: "On my way home after filming juice! Sooooo happy to be back! Was such a laugh!"
She also shared a picture of herself and Keith, adding the simple caption: "Reunited."
Fearne's return episode – which airs on ITV2 this evening (29 August) – will see her teamed with Doctor Christian Jessen and actor Ashley Walters.
On the opposing team, Holly Willoughby will be joined by TOWIE's Lucy Mecklenburgh and boxer Amir Khan.
While on maternity leave, Fearne had been replaced by Kelly Brook.
At the time, Fearne said: "I'm obviously gutted to be missing out on the new series of Celebrity Juice and will miss everyone a lot but am so happy Kelly will be joining the team until I'm back. She is used to Keith's ways, can hold her own and has ample assets to keep my seat warm till I'm back in September!"
Well, Kelly did her job and now Fearne's back in the spotlight.
We'll be tuning in!
