After dating for years, Selena Gomez and Justin Bieber parted ways. If the couple thought that would be the last for them, they may have been wrong.

A source apparently told Life & Style on Tuesday that by the end of October, the singer has started to feel nauseous and spent several days confined to her bed.

"After a week, her symptoms weren't getting any better," said the source.

Gomez and Bieber reportedly talked about being young parents before their relationship ended. The source said the "Come and Get It" star's face went "completely white" when she realized her sickness could be due to being pregnant by Justin.

She then reportedly had a "crazy anxiety attack" as she wondered if she was carrying his baby and she supposedly didn't go out on Halloween to avoid drinking under these circumstances.

The source says she had a friend drive her to the doctor for a blood test, but she stayed in the backseat of the car to avoid being seen.

When Selena found out she was not pregnant, the source said Selena felt like a weight had been lifted from her shoulders.

"She's happy she's not pregnant," the source said. "She wants to be done with Justin and is happy they won't be tied together for life - she would've been forced to put up with his lying and cheating forever."

While these two have had a messy breakup, they'll be able to avoid seeing anymore of each other for sure now.
