The Coronation Street actress achieved her highest score of the series with her Spice Girls routine.
And despite looking sensational in a Union Jack leotard and impressing the judges, Brooke couldn't hold back her tears after they had gave their feedback.
Jayne Torvill said: "Can't believe the confidence you've got in the last few weeks and so impressed you just took off there on your solo skate with such speed.
Christopher Dean added: "Five weeks ago I wouldn't think you were going to be here but three weeks turned around and your skate just got better and better."
Jason Gardiner agreed, saying: "I agree, I think this was a solid concept, I loved it and I think the choreography up until the solo skate.
"It lacked content, content that we know you are more than capable of delivering."
After some criticism from Jason, Ashley Banjo reassured her: "Out of everyone in the competition you have grown the most, to be here in the semi final to maintain that energy and confidence you have done so well. So be proud of yourself."
It's been an emotional day all round for the 25-year-old, who was pictured in floods of tears during rehearsals as well.
With two performances to contend with, Brooke clearly became overwhelmed by the tension as she sat on the edge of the ice in tears.
The emotional actress being comforted by her partner Matej Silecky, and then standing up to be hugged by a member of the crew.
During the show, the moment was shown to viewers, with Brooke explaining it was the fact she was skating to the Ariana Grande track One Last Time, which became an anthem in her hometown of Manchester following the Arena bombing tragedy last year.
She told Matej: "I'm sorry, there's just so much pressure on this song for me."
However her fears were unjustified as she beat her first performance to get another series high score of 34.5.
Jayne started things off by saying: "It was my favourite routine so far it had speed and flow."
While Chris added: "You did Manchester proud tonight, we loved the fact that you were enjoying it."
Even Jason was impressed, saying: "I dare say this routine was one of your best, it showed you have so much invested in it and you brought that to the ice."
Declaring how he felt she would make it to the final, he advised her: "You have to own those moments in the air, I wanted to see more, you need to live more."
Ashley added: "There were elements that we haven't seen in the last nine weeks so well done. after that I think everyone in Manchester will be behind you for sure."
