Stephanie starred in the last series of MIC after hooking up with Spencer Matthews, but she ditched him when he cheated on her. She then flew home to Los Angeles.
The Hills star is on English soil again, however, and has teased that she could be making a comeback in the E4 reality series.
Just before midnight last night (4 March), Stephanie tweeted: "Oh hey London... IM BACK!!!!!!!!! #secretisout yesssssss xxx."
oh hey London... IM BACK!!!!!!!!!— Stephanie Pratt (@stephaniepratt) March 4, 2014
Even Stephanie's sister-in-law Heidi Montag retweeted her post, adding to the speculation. #secretisout yesssssss xxx
Several of Stephanie's followers replied to her tweet, with one saying: "@stephaniepratt saw you in Gatwick with Lucy! You look fab x ;)."
Lucy Watson? Who knows - but we hope so!
In January, Lucy met up with Stephanie while on holiday in Los Angeles, proving they're still friends. They both experienced Spencer doing the dirty on them, after all.
Series 7 of MIC is already in production, so watch this space!
