Josh also took to Instagram to share the happy news, writing: "Our little family is getting a little bigger soon. 👶🏼 We are so so excited to meet you little one!"
The 26-year-old wore a stunning white cut out dress for the announcement and hundreds of her followers rushed to share their congratulations.
Elyse Knowles, who also recently announced she was expecting her first child with partner Josh Barker, wrote a message of congratulations.
“How exciting! Congrats guys,” she said.
Of course, the couple's "first baby" was there for the announcement too—their adorable dog, Ari Gold.
Congratulations to the parents-to-be!
