At the end of last night's show, viewers were given a preview of next week's episode where Stephanie interrupts Spencer's conversation with current love interest Emma Miller.
The Hills star Stephanie, who first appeared in MIC last year when she was dating Spencer, greets her ex saying: "Hey a**hole! You're such a piece of s***." Ouch!
Earlier scenes show Stephanie and Lucy Watson hugging, with Lucy asking: "Have you spoken to Spencer? I'm sure he'll be really surprised to see you!"
Well, he certainly was!
We're not too surprised to see Stephanie back on the E4 reality show, as in March, the reality star gave a strong hint that she was making a comeback after jetting into London from Los Angeles.
Stephanie has been staying with her "London bestie" Lucy since arriving back in Chelsea last month, and has been making friends with her other MIC co-stars.
Fans of the show will remember how Lucy and Louise Thompson teamed up to expose Spencer's cheating ways last year.
Lucy and Louise informed Stephanie of Spencer's infidelity, which left her heartbroken.
Before packing her bags to return to LA, Stephanie confronted Spencer and dumped him, with the pair leaving on rather bad terms.
Posting a photo to her Twitter account after the show last night, Lucy said: "On another note... Hey a**hole! She's back @stephaniepratt."
Stephanie said: "Really nice to be back in my favourite town!! Thanks guys xxx."
Spencer has so far remained quiet on Twitter, but we can't wait for all the drama to unfold next week!
