The 41-year-old singer-and-actress - who is joined on the panel of the TV talent show by Randy Jackson and Aerosmith rocker Steven Tyler - says the numerous years she has spent in the music business allow her to understand the predicament of the performers in the auditions.
Speaking on the Grammy Awards red carpet in Los Angeles on 13.02.11, she said: "I love it. Honestly, with all the experience I`ve had over the years, it`s like, what do you do with it? Steven, he`s been on the scene for 40 years touring. You have so much information, you have so much experience and so many little titbits you don`t even realise you have in your mind.
"You see someone perform, and you`re in the position to go, `Hey, you know what? Why don`t you think about this? You know what I see? I see this.` "
Jennifer - who is married to musician Marc Anthony, with whom she has two-year-old twins Max and Emme - also admitted she finds being a judge on the series "lots of fun"
