Snoop Dogg and Dr. Dre have reunited to work on new music.

The 'Drop it Like It's Hot' hitmaker took to Instagram yesterday (24.06.15) to post a photo of the pair in the studio together.

Snoop captioned the snap, ''Guess who bAcc (sic)'', alongside a host of emojis of fireworks, a gun, a microphone and a wad of cash, sparking a host of excited responses from fans.

Snoop, 43, was discovered by N.W.A star Dre in 1992 and after Snoop appeared on Dre's solo debut album 'The Chronic' the pair worked together on Snoop's first studio LP 'Doggystyle', which came out in 1993 and is widely considered to be one of the greatest hip-hop albums of all time.

As well as reuniting with Snoop, Dr. Dre, 50, also recently spent time with his former protégé Slim The Mobster in the studio.

Snoop's most recent album 'Bush' was released in May and was produced by Pharrell Williams.

On the record, the rap legend also collaborated with Gwen Stefani, Stevie Wonder and Kendrick Lamar on the LP.

While making the record Snoop gave some advice to 27-year-old rapper Kendrick on how to have a long-lasting career in the music business.

Snoop previously revealed: ''I told him to always challenge himself and be willing to listen. Always put yourself on a level where you're eye-to-eye with everybody. Never play bigger than anybody because you never know when it's gonna be over.

''He grew up watching his West Coast O.G.s, like Ice Cube, Eazy-E and Snoop Dogg. He had a pretty good blueprint to work with, and that's why he's doing it so well.''
