The singer - real name Lady … - performed a unique take on Usher track Without You on Saturday night's penultimate audition show.
Both Will.i.am and Danny O'Donoghue turned around, with Bo joining team Dany.
"I was completely terrified and I didn't really know what was going on and then bang, then Danny turned around and it was just awesome... he is awesome," Bo recalled this week.
Danny told her: "I came on this show to find unique voice, something that the second you hear on the radio it's gong to stand out."
Bo continued: "It was an honour to have him and will.i.am to turn around.
"I'm just so excited to sing in front of that many people that that's the dream, I#ve wanted my voice out there so knowing that a lot of people are going to watch this show is really really exciting."
Will Bo make it any further in the competition? We'll have to wait to find out!
