The two shared a short video on Instagram showing off Graham's growing bump. She wished her husband happy anniversary and said their lives are "about to get even better."
Ervin held a sonogram image on his Instagram account as he gave his 31-year-old wife a kiss on the cheek. He called Graham his "daily inspiration" and added: "I love you and I love us."
The two achieved couple goals last year when she posted a sweet tribute to Ervin on their eighth anniversary with "I love you, Justin and I can't wait to spend the rest of my life in your arms."
