The Hills star apparently flew all the way to the UK so she could be on the arm of Made In Chelsea's bad boy Spencer Matthews at the event.
It's no secret that Stephanie's big brother Spencer Pratt (one half of the infamous couple Speidi) was the bad boy of The Hills reality show and it actually lead to the two Spencers sharing love for each other in interviews.
Spencer Matthews has previously said of Spencer Pratt that "What he did for The Hills is epic! He made it very interesting and dramatic.
'I enjoy being the pantomime villain - and that is Spencer Pratt in a sense."
So was it those kind words that helped him to convince Stephanie to be his date?
Made In Chelsea star Spencer has made no secret of his admiration for Spencer Pratt and the pair are even thought to have met up in the past for dinner.
One person we don't think will be so taken with this new friendship would be Spencer's ex Lucy Watson who he admitted cheating on only weeks after saying he was falling in love with her.
But not to worry, Lucy was on her own date last night with rugby star Jordan Turner Hall so two can play that game.
Reckon Spencer and Stephanie could be a new couple?
