Isaac’s a big brother again! On Sunday, Oct. 4, Teen Mom 2 star Jo Rivera and his longtime girlfriend, Vee Torres, welcomed their baby daughter. The reality stars named the little girl Vivi

Torres posted a photo of herself in the hospital prior to going into labor on her personal Facebook page, writing, “On my way to you mommy — Vivi. this has got to be one of the hardest days to have gone by, but waiting for that light at the end of the tunnel!” 

She also posted a photo of proud dad Rivera with his baby girl in his arms, which he promptly made his Twitter avatar image. 

Little Vivi is the first child of Rivera and Torres, though the Teen Mom 2 dad shares son Isaac, 5, with his ex Kailyn Lowry. Lowry and her current husband, Javi Marroquin, also share son Lincoln, 22 months. 

In last week’s previously taped reunion episode, Lowry and Torres addressed the rumors that the Teen Mom wasn’t happy for her ex and his girlfriend on their new baby. 

“I have no hard feelings toward her or her unborn child!” the mother of two told host Dr. Drew Pinsky

“And I know that,” Vee replied. “People were making it seem like she was like, ‘I don’t want to f—king deal with her baby!’”
