The series one original made a surprise return to the Newcastle house on the first episode of Geordie Shore: Big Birthday Battle, which celebrates five years since the programme debuted on MTV.
And she's now told fans she's thrilled to be back.
Taking to Twitter after the episode aired, she said: "Feel on cloud nine right now. What an amazing year I'm having. Thank you everyone love you all so much man wish a cud hug all of yaz (sic)."
Fellow Geordie Shore star Kyle Christie tweeted: "Really proud of @SophieKasaei_ tonight on #Geordieshore she came in with an absolute bang finally back were she belongs!"
While Holly Hagan simply said: "OUR SISTA IS BACK."
Sophie entered with a bang on Tuesday night (10 April), stunning all the housemates who hadn't been expecting to see her - especially Charlotte Crosby, who broke down in tears: "She was the first friend I made here and to see her face walk through that door, I can't describe how happy I am."
Her cousin Marnie Simpson was also speechless: "I don't think I could ever have had a bigger, better surprise. This has literally made my life!" Gaz Beadle added: "She was like a little sister, it's just so nice to see her."
Sophie was axed from the show in 2013 after she was accused of making an racist comment on camera. She told Daily Star this week: "It was the biggest mistake of my life. It's the biggest regret and I am sorry. I had the best job in the world and to lose it was awful."
"It's been so long since I wanted this to happen," she said last night. "I'm finally back with my best friends."
Plenty of viewers were also pleased to see Sophie back:
