Paging Alex Da Kid. The British producer steps into the E.R. with Dr. Dre on set of “I Need a Doctor,” the Detox single which he produced. The hitmaker tweeted a pic from the shoot, chucking up the deuces and sticking his tongue out at the camera while wearing a white lab coat with a medical cap on his head.

Eminem was also snapped arriving to the L.A. set last month. Allen Hughes, the director behind Menace II Society and The Book of Eli, is at the helm.

“Doctor,” which features vocals from Skylar Grey, is shaping up to be another hit for Alex. It has already reached No. 1 on the iTunes Top Songs chart after only a few days of release.
