Fifth Harmony made their UK debut by performing their latest single Boss, on The X Factor stage tonight.
The five-some have made it to the number 1 spot in 19 countries.
After their performance Dermot O’Leary gushed: “That’s the way to get the party started.”
And he was right, the girls not only got us, but all four judges – Simon Cowell, Cheryl Fernandez-Versini, Mel B and Louis Walsh – out of their seats dancing.
When speaking to Dermy after their performance, they spoke to the ITV show’s presenter of their recent trip this week to the White House.
The girls were very, very eager to boast that the President’s wife, Michelle Obama, listens to their song.
And of course that “they love the UK,” is what the girls screamed in unison in Dermy’s face.
Also, winner of last year’s X Factor, Sam Bailey returned back to the ITV shows’ stage to sing her new single, She.
Accompanied by a live piano the 37-year-old left us all in goose-bumps.
A very humble Sam, spoke to Dermy of being back on stage and said: “You know what it’s so scary and I’ve been treated like royalty.
“After last night’s performance I have to say Fleur East,” is who Sam is backing, with no hesitation, to win the show.
