You might have seen the bw version of this photo a few days earlier.
This photo shows Eminem, FredWreck, Mr. Porter and Snoop Dogg in Detroit studio. Snoop was performing in Detroit that day, and maybe he just used an opportunity to meet with his friend and hip-hop colleague.
Supposedly, Em and Snoop might have recorded a track ( or several!) for upcoming soundtrack to “Bodied” movie. If track does exist, it was probably produced by FredWreck and Mr. Porter.
