You never know where Eminem is going to pop up these days. The often reclusive rapper has been more visible lately as he promotes his latest album, The Death of Slim Shady (Coup De Grâce), including a totally surprising hop-up in London on Thursday night (July 18) to support his old friend and mentor Dr. Dre.

Marshall surprised the crowd at the launch event for Dre’s new canned drinks line with Snoop Dogg, Gin & Juice, when he jumped on stage at Flippers Boogie Palace to join the party hosted by former NBA great Shaquille O’Neal. But first, Dre and Snoop rolled through a set of some of their most beloved songs, including “The Next Episode,” “Drop It Like It’s Hot” and “Nuthin’ But a G Thang” at the event attended by Lakers legend LeBron James and Idris Elba, among others, according to NME.

Near the end of the set Dre introduced Eminem, who ripped through the first single from The Death of Slim Shady, “Houdini,” before the pair moved into “2001” and “Forgot About Dre.” Em posted video from the exciting surprise mini-set of him performing a bit of his “Without Me,” writing, “London thank u!!! Had 2 pullup 4 @dreandsnoop at @flippers.world.” He also posted a gallery of photos from the night featuring images of a low rider tipped up on two wheels outside the club, as well as shots of Dre and Snoop performing and his surprise set.

Though Em has not announced a run of dates to support his new album, he will appear alongside Muse, Thirty Seconds to Mars and Richie Hawtin at this year’s Soundstorm festival in Saudi Arabia in December.
