Kendrick Lamar called out rappers by name in his infamous "Control" verse released in 2013, but the internet is playing the guessing game about his target in a new song.

Lamar released "The Heart Part 4" on Friday and caused a frenzy on social media as fans tried to figure out who the rap prince was referring to in the track.

Drake, Big Sean and J. Cole were some of the rappers speculated to be Lamar's target on the song, which starts with the line, "Don't tell a lie on me/I won't tell the truth about you." On the second verse he raps, "Tiptoeing around my name … you lame."

The rapper, 29, also name-drops President Donald Trump in the song, calling him a "chump."

Lamar is expected to release a new album this year. It will be the follow-up to 2015's Grammy-winning "To Pimp a Butterfly."
