This week marks the end of TOWIE's twelfth series and loved-up couple Jess and Ricky have swapped hearts and flowers for their game faces and a whole lotta muscle.
It was competition time for this lovely duo as they challenged each other to an arm wrestle!
They may have been all smiles to start with, but we wonder who came out as champ....
Channelling movie classic and all time favourite Grease, Jess and Ricky joined their Essex pals as the TOWIE cast went out in force with their fancy dress outfits.
Born to be a T-Bird, Ricky worked his 'Grease Lightening' look all the way down to his white socks and shoes. Sporting a tight black tee and trousers, all the cheeky chappy needed was his T-Bird leathers to finish his look.
One thing he wasn't missing though was his pretty Pink Lady.
Working Sandy's 'good girl gone bad' image, Jess sizzled in skin tight leather and a black off-the-shoulder top. Injecting a little 1950s glamour into her outfit, Jess sported a cute polka dot neck tie and a stylish pair of red wedges on her feet.
The TOWIE beauty, wore her ombre locks in tight curls around her shoulders and added some sass to her ensemble with a bold red pout and matching mani.
Last week, Ricky proved Jess is the only one he wants while attending Leah Wright's wedding in Spain. Gushing over his girlfriend during last Wednesday's (23 July) TOWIE episode, Ricky said he had fallen in love with Jess all over again after seeing her in her bridesmaid get up.
What a cutie!
But never mind their arm wrestling competition, Essex's reigning power couple could have a fight on their hands to retain their title.
This series, viewers have seen love blossom between Elliott Wright and Chloe Sims, with Elliott even declaring his love for Chloe on screen.
Joining Jess and Ricky at the Grease-themed bash, Elliott and Chloe looked seriously hot as they channeled Danny and Sandy for the do.
And inspired by Rydell High's love story, could Lauren Pope and Lewis Bloor be Essex's latest official romance?
Although the couple are yet to label their relationship, Lauren and Lewis sure looked smitten as they kissed at the Grease party...
Catch the TOWIE finale this Wednesday 30 July at 10pm on ITV2.
