Spoiled Milk married Filthy Rich for his money, everyone in Ponyville but him knew that.
In a loveless marriage, Spoiled Milk had a affair with a pony she met during a Canterlot party and gave birth to Coronet. Filthy Rich, a person who wanted to keep appearances bargained to raise her as his daughter, but trouble came their way when the biological father argued over custody and Spoiled Milk frivolously gave her daughter away without a second thought.
In order to save their marriage Filthy Rich and Milk had Diamond Tiara. Coronet had lived with her bio-dad. Spoiled Milk had completely ignored Coronet and refused to acknowledge her ‘mistake’ as she tried to make Diamond Tiara into the perfect daughter. At this point Filthy Rich stopped focusing on his wife and instead did his best to try to raise his daughter right.
For a long time Diamond Tiara never knew she had a half sister, but Coronet was painfully aware, Coronet was jealous of Diamond Tiara for 'stealing' her mother away from her, her bitter feeling faded and she instead focused her resentment on her mother.
It was only after Diamond Tiara inherited her fathers money after his death and read his will did she learn that she had another sister. She was given the choice to split her money with her sister. Despite Spoiled Milk trying to manipulate Tiara for her fathers money; Diamond Tiara and Coronet began to bond over their hatred for their mother and effectively renounce her from their new family.
