At age 16, Karen gave birth to her eldest child Chantelle. Shortly after she fell pregnant again with a second daughter, although she lost the baby. She nicknamed her unborn baby Lumpty Dumpty when she lost her. Karen thought she would not have any more children but she went on to have five more children by several different fathers.
In December 2017, after Lauren and Abi Branning fell from the roof of the Queen Victoria, Karen, Sharon, Linda, Shirley and Tina can be seen in the stairwell laughing as Mick walks in. He appears angry, and asks if they heard the sirens. Mick tells them that he better make an announcement. He proclaims that there has been an accident, as the police and Keegan Baker walk in.
In January, Karen thinks she has secured a job at the laundrette, however when she turns up she is shocked to discover Masood working there. Mr. Papadopolous tells them that he will give them both a trial - whoever does the best job, gets the job.
In November, shortly after Shakil's stabbing, Traumatised Keegan raises a knife to his own mother. Thankfully, Karen persuades him to put the knife down, but brutally punches him in the face, shouting at him about raising a knife to his family.
After Karen is informed of Keanu and Sharon's secret affair as well as Keanu being away after seeing a picture of his bloodied face, she rushes to Phil's house and grabs Sharon and threatens her. Even with this happening, Karen still heavily dislikes Sharon due to the disastrous affair. In July, Karen told her family that she was now a lesbian and that she was seeing a woman called Caren. In August, however, after having their first kiss, Caren quickly got up, left the house and rejected Karen. It is unknown whether Karen will stay lesbian or simply needs more time to find the right relationship.
