'I was very excited to find out I was pregnant. I wasn’t sure if it was going to be possible since I was diagnosed with endometriosis when I was younger,' she said.
The 33-year-old added: 'We both really want a little boy, but we wouldn’t be disappointed to have a little girl! All that really matters is that the baby is happy and healthy.'
Sam is currently engaged to Chris Wise, who proposed on his birthday while they were in Atlanta.
