The actress, who plays Sophie Webster in the ITV soap since, marked exactly 12 years since producers gave her the part as Sally and Kevin Webster's daughter.
Brooke tweeted: "Today 12 years ago I got the part of Sophie Webster!!! I think 12 years on they are still regretting that decision."
And, just in case she needed a trip down memory lane, her co-star Alan Halsall shared an old video of the actress making her first appearance on the cobbles.
Alan said: "You should be proud of your 12 yrs & I hope there's many more."
Brooke made her on-screen Corrie debut in May 2004, taking over the role from Emma Woodward, who previously played the character.
