The rapper/producer will appear at a pop-up photo booth in Covent Garden at 3pm

Dr Dre is to make a rare public appearance at a Beats By Dr Dre event in London this afternoon (November 9).

The rapper/producer will be appearing at the ‘Beats By Dr Dre Show Your Colour’ photo booth, which has been set up in London’s Covent Garden, at 3pm today.

The pop-up photo booth gives fans a chance to star in the next TV advert for the Beats Solo HD range of headphones. You can enter the competition by stepping into the booth and getting your picture snapped. Dre himself will also enter the booth.

Ten lucky winners, chosen by Dr. Dre and Interscope-Geffen boss Jimmy Iovine, will be flown to Los Angeles to film the commercial and receive a pair of Beats Solo HD headphones and a HTC smartphone.

Last month, Lil Wayne revealed that he has recorded close to 100 tracks with Dr Dre, all unheard by the public. “I’m not sure if you know how Dre works,” said the Young Money rapper, “Dre always sends you a song, so I done, probably did like 90 songs for Dre. You just never know which one he gonna put out.”

Meanwhile, 50 Cent shared his belief that Dr Dre’s long awaited album ‘Detox’ may only surface as an EP given Dre’s various business and TV ventures.
