Watchout! is the fourth studio album and fifth album overall by Martha and the Vandellas, released on the Gordy (Motown) label in 1966. The album included the top 10 hit singles, "I'm Ready for Love" and "Jimmy Mack" and the ballad single, "What Am I Gonna Do Without Your Love?". This was one of the last albums by the group with songs by Holland–Dozier–Holland who, the following year, left Motown, and with William "Mickey" Stevenson, who helped put the group on the musical map. The title of the album was derived from a song on the B-side of their hit single "My Baby Loves Me" (released earlier in 1966) entitled "Never Leave Your Baby's Side" (never released on an album). That song's chorus warned to "Watchout!" for "other girls" who could steal your man.
