"I am due Jan. 29, 2018! I am 15 weeks along now," Reinhardt, who is already mom to daughter Kensington, exclusively tells ET. "Kensington will be turning one in a few weeks, so our babies will be 17 months apart. Two babies under two years old!"
"I am feeling amazing and haven't had a day of morning sickness during this pregnancy! I was sick everyday for the first 15 weeks with Kensington," she adds. "This has been such a great pregnancy and, most importantly, our baby is doing so well and is so healthy! I am craving everything spicy and salty!"
Reinhardt and Brown, who know the gender of their baby but are waiting to reveal it, are "very excited" about what they're having -- and say their daughter is too.
"Sean and I keep telling her she's going to be a big sister and she understands the excitement and happiness, but she's only 11 months old, so I don't think she quite understands that she is going to have a sibling soon," Reinhardt explains. "She loves other babies though, so we are all so thrilled for our little love to arrive."
