At Macy's Glamorama event in L.A. Friday, their mom, Camila Alves, opened up to Us Weekly about what her two kids with Matthew McConaughey make of her burgeoning belly. (After tying the knot on June 10, Alves, 30, and McConaughey, 42, announced they're expecting their third child on July 4).

Alves revealed that there's a lot of baby-related excitement in their home at the moment.

"They love [my baby bump]," the handbag designer told Us. "I think they fully understand that it's a little baby coming. They love it."

And in general, she said her two older children are "doing great."
