Def Jam Vice President of A&R, Lenny Santiago, gave fans a treat on Thursday when he posted a picture of Timberlake, Jay-Z, Nas and Timbaland in the studio together on Instagram.

In the caption, he wrote, "JAY x JT x NAS x TIMBO Rat Pack shit. For some this is "Work"... For us it's just Fun. #RocNation.”
