The star also uploaded a photo to Instagram that showed off her engagement ring.
“Last week the love of my life pre-wifed me... I can finally let myself go. Couldn't be happier. Luckiest girl in the world,” she captioned the pic.
After engagement rumours began circling last month when she wore the pearl ring, she told 2GB that while she’s “desperate” to get married, she wouldn’t want the pearl ring as an engagement ring.
"I know I said I’d accept a burger ring from Sean because my standards are low and I am desperate, but I would not accept a costume ring," she said at the time. "I am definitely not engaged!"
After being asked what her response would be if the 41-year-old were to propose, she replied: "Well, if you really want to know, I’ve never had anyone ask me before. It’s got to be special."
Speaking to the Daily Mail last year, Erin confirmed that she is "very much in love" with her policeman partner, who she began dating in March 2016.
"I think it's for life. He is a good boy, so we will see," she continued. "We sit at home and literally watch the football, go to the local pubs and we go to our parents houses."
