Stephanie, who rose to fame in US reality show The Hills, was pictured on set in Knightsbridge, London, alongside the former couple yesterday (7 August).
We are especially delighted to see Stephanie is joining the Made In Chelsea cast, as we have been championing E4 to give her a part for weeks!
With her hands clasped in front of her, Stephanie rocked back on her heels as Spencer gave his ex-flame Louise a giant hug while the cameras rolled. Awkward!
She did, however, managed to give Louise a wry smile.
The trio were also snapped in between takes, but with them all looking in a different directions, we're wondering if the air could have been cut with a knife!
Spencer - who idolises Stephanie's brother Spencer Pratt - began dating the blonde earlier this summer and they seem genuinely loved-up.
We can't wait to see the drama unfold when the new series begins this autumn. Bring it on!
