|“||Ben! (Ben: I don't want you to be my mum!) Come here, Come here! I will kill you in your sleep if you don’t walk through that door; I will come to you in the night and I will suffocate you in bed! And your daddy will find your little dead body in the morning, he will have to bury you in the ground just like your mummy!||„|

|~ Stella's last words before her death.|
She was portrayed by Sophie Thompson.
Stella was Phil Mitchell's new lawyer and they later began dating, but Phil's son Ben was unhappy about it. Stella tricked Ben into trusting her and tried to end his friendship with Abi Branning before eventually starting to abuse him. She then forced Ben to convince Phil to propose to her which Phil did and she accepted. The abuse continues with Stella calling Ben names and making him confess to things he never did. She once came to Ben in his room and said that she loved him, but she only said it because Phil was listening. After foiling Ben's plan to run away with Abi, Stella smashes a photo of Ben's mother Kathy and said that he is too pathetic to be Phil's son.
On the day of Stella and Phil's wedding, Ben tells Stella that he does not want her to be his mother to which Stella warns him to keep quiet. Halfway through the ceremony, Ben reveals what Stella has been doing to him. Stella flees to the Queen Vic, where she pours orange juice on Ben's bed to make it look like he wet the bed before tearing a photo of Ben and Phil in half and tucking the part with Ben on it in her bra. She is found by Phil who follows her to an abandoned factory where she locks the gates so Phil can't get to her. Stella tells Phil that in childhood, her parents blamed her for her sister Catherine's death and was treated like a ghost in her own home. Phil drives his car into the gates and runs after Stella onto the factory's roof where she threatens to jump unless Phil says he loves her. Phil replies that he chose her because he thought she was convenient for Ben and would be a good wife.
Stella jumps off the roof whilst clutching the photo of Ben, lands on the wedding car and is killed instantly. Phil was initially arrested for murder, but CCTV shows that she jumped.
