The singer didn’t win the show on Saturday night, but her original EP has rocketed on the iTunes chart.
The mini-album – which was recorded and released before the show – is currently sitting at number 2 in the charts.
It’s overtaken the likes of Coldplay and Paloma Faith, while also beating actual Voice winner Leanne Mitchell.
Her winner’s single, a cover of Whitney Houston’s Run To You, is just outside th Top 30 in the singles chart.
Writing on her blog, Bo said;: “I can’t quite believe what’s happening – I can’t thank you all enough… and I’m not sure I’ll ever be able to – other than to keep making music for you.
“But thank you, thank you, thank you all so much for the tweets, the emails, the love and of course ……the votes.”
Speaking about her record, Bo went on: “Thank you to everyone who bought it. I was beginning to think that no-one would ever hear it..and now its overtaken Coldplay ;-)
“Whatever happens next, I will most definitely be making an album – and quickly – I will keep you posted on facebook, twitter, my website and whatever else they invent.”
She added: “My time on The Voice was insane. To think I was so cautious and unsure about entering in the first place… I never imagined I would get be ME throughout- and make it to the final.”
