Ariana Grande has been delighting us like clockwork with her new R.E.M. Beauty launches. Chapter 1 brought us matte liquid eyeshadows, Chapter 2 brought us precision-unmatched eyeliner markers, and Chapter 3 brought us incredibly shiny blush and lip stains. Now, with Chapter 4, Out of Body, officially launched on Ulta.com and in select Ulta stores, it's time to discover new must-haves. And who better than Ali himself to guide us through our shopping journey?

Of course, she is equally enamored with each and every product in the line. But her brand's latest line of products for the complexion holds a special place in her heart. The R.E.M. team and I have been working on this launch for a long time. I actually secretly wore this concealer during the filming of 'The Voice,'" Grande told Marie Claire exclusively. I can't wait for everyone to visit Ulta Beauty and try this amazing skincare-infused formula for themselves! Grande told Marie Claire exclusively.

Here, the "7 Rings" singer breaks down exactly what she loves most about her new launch.
