I had to read this headline more than once because I was so confused! A teen from Brazil gave birth to twins but the twins have different biological fathers. If you are as confused as I was, this woman ended up have intercourse with two different men on the same day. Resulting in her being pregnant by two different fathers. They figured this out because although the babies looked alike, when they did the paternity test with the man whom she thought was the father, he was only biologically related to one baby. This is extremely rare because there are only about 20 cases similar to this one in the world.
