Trouble (*Lilo/One Direction fanfic*)

Isabella Tomlinson is Louis Tomlinson`s sister, but not many of the fans know about her. She`s not one that likes the spot light.
She moved to London when she had finished school, when she was 16. Now, she`s almost 18, and pregnant, but, her boyfriend kicks her out.
When she only has her brother to turn to, he is glad she`s pregnant. It pulls them closer than before, but when Louis realises Isabella and Liam are falling for eachother, he also senses there`s something fishy going on between Zayn and Perrie Edwards.
What will happen when Isabella and Liam become official after the baby is born, or will something spark between Bella and Niall instead?
