Abit concerned for my sister..

Right my sisters husband a while back had a 1 night stand with a women he says he doesn't remember. (Drunken mistake) He says. My sisters bestfriend also happened to of had a 1 night stand with a male. Due to a month later she found out she was pregnant.

Now my sister has 4 kids with her husband. All girls😂 She has been very supportive of this bestfriend and her pregnancy. Fastforward 9 months the baby is born.. Its a Girl. This baby is now 4 weeks old. My sister came to my house crying her eyes out.. She was saying how much this baby looks like her husband and 4 daughters. Now she wasn't wrong. She was saying how they both had a 1 night stand around the same time.

Now i said to her to not freak out yet and ask for a DNA on the baby and her husband.. What are your thoughts on this ladies!? I will be posting updates!.
