Is this "Teen Mom 2" ... or "Maury"?

The MTV reality show took a turn towards talk show territory last night when Jenelle Evans took a paternity test to find out if her ex-boyfriend Andrew was actually the father of her 2-year-old son Jace.

You see, last week she revealed that she also hooked up with her BFF's boyfriend right around the same time she got pregnant. What a friend, right?

After hearing that news, Andrew told Evans he was 99.9% sure Jace wasn't his son.

So ... was he right?

Check out Evans getting the results of the test above. Her mom, Barbara, was not happy with the answer.

And ... because it never gets old ... check out this hilarious compilation of "You Are NOT the Father" moments from "Maury":
