Louise told fans earlier in the day that she was on her way to filming but later this afternoon revealed that she had found herself shopping on Oxford street - and it appears Stephanie has been joining her for the ride!
Early last month, The Hills star Stephanie prompted rumours that she was making a return to Made in Chelsea after flying into London from her home in Los Angeles.
The first episode of series seven kicked off last night (8 April), and there was no Stephanie in sight, but seeing as it's just started, there's hope yet!
Louise posted a photo of Stephanie on the tube this afternoon, saying: "Public transport day out with @stephaniepratt ..... She so doesn't know how to handle herself."
Stephanie also went around Buckingham Palace and posted a photo of the horses on Twitter, before writing: "Passing the guards this am."
Stephanie starred in the last series of MIC after hooking up with Spencer Matthews, but she ditched him when he cheated on her.
Before flying back home to Los Angeles, Stephanie struck up a friendship with Spencer's exes Lucy Watson and Louise. Seeing as Stephanie is now back in the popular SW3 postcode, we're desperate to know if she's bumped into Spencer yet!
