In March, Bookout told PEOPLE Bentley — her son with ex-boyfriend Ryan Edwards — was looking forward to being a big brother.

“He’s so excited for the baby,” the mom-to-be said of her 6 year old. “And I’m excited for him to have a sibling. I think it will be good for him to finally have to share the spotlight.”

So with everyone settling into their new roles, could wedding bells be next? “We definitely want to get married and we’ve talked about it a lot,” Bookout has said.
