The X Factor judge, who saw a large number of Adele covers on this series' auditions, revealed that he shared his view with the 'Someone Like You' singer herself.
Speaking on Chris Moyles's Radio 1 breakfast show, Barlow recalled: "She came to one of the Wembley shows and I said to her, 'I've got to be honest, I'm really sick of your album because it's all that's been played at X Factor'."
The Take That singer continued: "This year has been all Adele. We're sick of Adele."
However, Barlow claimed that she "completely understood" his sentiment.
The 40-year-old star went on to say that he has become irritated with Lady GaGa's material too, adding: "We've really had enough of them two."
