EMILY Atack looked sensational as she posed in a bikini for behind-the-scenes Rivals. snaps

Based Jilly Cooper's 1988 novel, Rivals launched on Disney+ on October 18.

Former Inbetweeners star Emily, 34, plays the character Sarah Stratton.

Taking to Instagram, Emily shared on the on-set bikini snaps with the caption: "What ep are you on?"

One fan replied: "Episode 6…second viewing!!!! So good I’ve had to watch it all twice!"

Another commented: "Watched all of them. We need a second series."

Set in the Eighties in the fictional county of Rutshire, long-held grudges bubble to the surface as the characters vie for business and each others’ affections in the cut-throat world of telly execs. 

Rivals' all-star cast also includes David Tennant, Danny Dyer, Aidan Turner and Katherine Parkinson.

Less a month after its release, the Disney+ show's future has already been confirmed.

Early screenings were said to have impressed bosses at the streaming giant.

A TV insider said: “The feeling is that there is still so much more in the story that could easily be made into a sequel.

“Disney+ appear to be on board, even though they haven’t announced an official commission yet.

"Bosses at the streamer can see there is a huge amount of anticipation for this show, and having seen the episodes, they know it won’t disappoint.

"So going for a follow-up is a no-brainer, though these things take money and time, particularly as they have to try to align the very busy diaries of Rivals’ star-studded cast.”

It comes as fans were left raving over the raunchy new series.

Taking to social media, one wrote: "I f*****g love #rivals on #DisneyPlus so glad it hasn't disappointed me as it is my favourite book ever (and no I'm not embarrassed to admit it)."

Another added: "Episode one done. It’s magnificent! Well done @DisneyPlus and Dame Jilly. #Rivals."

A third chimed in: "#rivals everything I expected and more! 80s hair, music and debauchery! I love it!"

While a fourth remarked: "Im loving this show!!! #rivals #hulu."

Rivals is streaming on Disney+.
