Kathie Lee's daughter and Cody's 25-year-old sister, Cassidy, also shared the news on Instagram, writing: "So excited for what God has in store for these two. The most excited to welcome my already sister @missamerikabrown into the craziness."
The bride-to-be posted the same photo as Cassidy, simply writing: "𝐑𝐈𝐍𝐆 𝐀𝐑𝐎𝐔𝐍𝐃 𝐓𝐇𝐄 𝐑𝐎𝐒É ❤️ #thebestgiFFt 💍 #loveisthegreatestgiFFt."
She also took to her Instagram Story to gush over her engagement, that apparently was not expected. "What started as a fairly normal weekend has turned into the BEST EVER," she wrote. "Couldn’t be happier!"
The newly engaged couple later went to the Florence + the Machine concert in Santa Barbara, California, and Erika quoted the band on Instagram, writing: "It's such a wonderful thing to LOVE!"
