Remember when Wesley, Keaton, and Drew performed this fun mash up of The Temptations “My Girl” and Katy Perry’s “California Gurls” on X Factor last year? We do!

Not only do we get to see a great performance, but we get great insight into Emblem3’s beginnings. This exciting jam is the perfect blend of the boys’ rock/pop style where they get to highlight their Cali upbringing.

The cuties of Emblem3 were loved by LA Reid and Britney Spears, but Demi wasn’t too happy about Simon plugging 1D having “What Makes You Beautiful” play as the backing track.

How did you like this mash-up? Do you agree Demi? Will you be buying their debut CD? Tell us on Twitter and in the comments!
