"We are beyond excited to finally announce that we’re expecting baby number two!!" the 32-year-old bridal gown designer wrote on Instagram alongside cute pictures of her and her husband with Asher, reading a book titled I Am a Big Brother. "And it’s safe to say after Asher realized he was going to be a BIG brother he wasn’t so happy! Lol. Actually he just didn’t want to take direction (what kind of toddler is he?) and had a tantrum BUT we are glad to share our good news with you all and can’t wait to take you along for the ride!"
