Rivera and Torres began dating in 2012, following Rivera's breakup from Lowry, with whom he shares a young son, 5-year-old Isaac.

After their split, Lowry went on to date Javi Marroquin, whom she later married and had a second child with.

As fans of Teen Mom 2 saw, Lowry married Marroquin in a courthouse ceremony in September 2012, and then again in a larger ceremony in September 2013. One month after their second wedding, Lowry and Marroquin welcomed son Lincoln Marshall Marroquin, and although there have been reports of a possible third child for Lowry, she recently denied any plans for more children.

Torres spoke out about her pregnancy on Twitter, as well.

"I'm so overwhelmed with emotions right now," she wrote. "Literally went from pissed, to crying, to smiling, to crying back to happy again oh pregnancy."

Jo Rivera will return to MTV in Teen Mom 2 season six, which is currently in production and expected to premiere later this year.
