Super-producers Dr. Dre and will.i.am combined forces at the Beats by Dr. Dre pop-up store opening in New York City on Wednesday (Nov. 2). The hip-hop pioneer, whose Detox release date still remains a mystery, showed off the brand’s holiday lineup and celebrated with a cake in the shape of a headphone.

The Black Eyed Peas frontman recently shot a video for “T.H.E. (The Hardest Ever),” his collaboration with pop icons Jennifer Lopez and Mick Jagger, and is prepping his next solo album for release in the new year.
