After 17 Years of Friendship, American women discover they are sisters!

 A pair of Pennsylvania women who have been best friends for 17 years said they were shocked to discover after all this time that they are biological sisters.

Ashley Thomas, 31, and Toya Wimberly, 29, said they met in Year seven at Sulzberger Middle School in Philadelphia and the pair soon became inseparable.

Thomas' late mother's best friend was recently scrolling Facebook and came upon pictures from Wimbery's engagement party. She spotted Wimberly's father, Kenneth Wimberly, in the photos and recognized him as someone who used to spend time with Thomas' mother.'

Kenneth Wimberly said he remembered the women and the group soon started to suspect he might be Thomas' biological father. A DNA test was conducted and confirmed the suspicions.

Toya Wimberly said in a Facebook post that the revelation has only strengthened their bond.

"That's why we're so similar, that's why we look so alike, that's why we've been inseparable since the 6th grade," she wrote.
