Louis Walsh has declared "the bitch is back" after taking Sharon Osbourne to his X Factor judges' houses.
The pair are currently in Las Vegas filming the last audition section of the show before the live finals.
Discussing her relationship with Louis, Sharon, who was an X Factor judge until 2008, said: “It’s like riding a bike, you never forget.
“The magic that comes from the two of us rubbing together, it’s electric.
“We could cause lightning because we are like lightning in a bottle."
Speaking about the acts in Louis' still to be confirmed category, Sharon added: "I am looking for an act that can take Louis to the winning place of The X Factor this year.
“Louis has to win this year and we are going to find him the act that will take him all the way.”
Meanwhile Louis declared: “The bitch is back – it’s Sharon Osbourne."
Explaining why he chose the flame haired reality star to help him out, Louis explained: “She is just honest. She is a self-made person and she just speaks her mind.
“She is just different. She is a bit mad but in a good way and that’s great.”
He added to the Daily Star Sunday: “She is more experienced than anyone else. There is nothing this woman hasn’t done or said.”
