Singing duo Makenna and Brock sang in perfect harmony at their audition, but when questioned about their relationship they were much less in harmony.

Performance Summary Age : 22 and 18. Auditioned In : Chicago. Song Title : Colder Weather. Recorded By : Zac Brown Band . Available From : Amazon.

The duo sang ‘Colder Weather’ by the Zac Brown Band which was a big hit with the audience. They’ve made LA’s day, and Cheryl Cole said that the harmonies were “spot on” and appreciates the control they had of their vocals.

However, before they sang, Simon wanted to know about their relationship. They said they were just friends but their body language was telling a different story. Brock looked heartbroken when Makenna insists that they’re just good friends. Check out the moment in the video below:
