The 26-year-old, who lost out to Anton Stephens during the results show, after the judges sent it to deadlock, allegedly taunted the girlfriend of the man she had a three-year affair with.
According to The Sun, while Monica was enjoying a romance with Ashley Fenton-Burgess, his girlfriend Ellen Hanley raised their son.
But Monica reportedly rubbed salt in the wounds, by telling Ellen: “I’m glad I hurt you so much. I’m delighted your family’s ripped apart. No regrets.
“So f*cking what if I’m a bitch. Wish you all the unhappiness in the world – oh wait – I’ve done that already.”
Shockingly, after she stopped seeing Ashley, Monica is said to have told Ellen she only started a relationship with him to spite her.
A former friend of Monica’s told the publication: “The girl is just evil. She tormented Ellen and left her in a mess. Her whole life was in ruins for a long time.”
The Sun claims that, while Monica admits she and Ashley were in a relationship, it was nine-months before she found out about Ellen.
It’s been a controversial 24-hours for youth worker Monica, after she was forced to apologise for making a gun reference following her X Factor elimination.
After some viewers claimed it was inappropriate given the recent tragedies in Paris, Monica tweeted: “I want to apologise for any offence caused on @TheXFactor tonight. I wasn’t thinking beyond the moment & iy was insensitive, sorry [sic].”
