“I love him!”

Catelynn Lowell’s young daughter Novalee is thrilled with the news that she is going to be a big sister in a sneak peek of the upcoming Teen Mom OG clip and she may have revealed the gender of the new baby.

While decorating pink and blue cupcakes with her younger child pregnant Lowell revealed the joyous news, telling Novalee: “Mommy has a baby in her belly.”

The MTV star was thrilled to share the news with her younger daughter after tough times, including rehab and a tragic miscarriage.

She asked Novalee if she wanted a brother or a sister and she first says a “little sister,” much to her parents’ seeming chagrin.

“What if it’s a boy,” dad Tyler Balterria asked.

“Would you be happy to have a little brother too?” Catelynn asked Nova.

“Yeah,” she says

“I will rock it and feed it bubbles,” the proud “big sister” tells her mom.

“I love him!” Nova tells her mom.

Earlier this year, Breaking Celebrity News reported the couple was suffering marital problems after the reality TV mom returned to rehab to deal with her miscarriage and ongoing postpartum depression.
