Anansa Sims Expecting Second Child

The plus-size model and her husband, David Patterson -- who are already parents to 9-month-old daughter Ava -- are "very, very excited," she tells PEOPLE exclusively.

There’s another baby on the way for Anansa Sims!

The plus-size model, 33, and her husband, David Patterson — who are already parents to 9-month-old daughter Ava — are “very, very excited,” she tells PEOPLE exclusively.

And though the expectant mom “is hoping for a boy” this time, she would also be “totally fine with [Ava] having a sister close in age.”

Someone else who’s just as thrilled about the fall arrival? Sims’s own mother, former supermodel Beverly Johnson.

“I was excited the first time, but I think I’m more excited this time because you see how much joy Ava brings and how much love you have,” the proud grandma, 59, tells PEOPLE.

Sims and Patterson tied the knot nearly two years ago in Ohio. The family reality show, Beverly’s Full House, airs Saturdays at 10 p.m. on OWN.
