And we've fallen back in love with Shia LaBeouf again...

He may have all sorts of issues, but the actor also has some serious rapping skills, as evident from his appearance on the the "5 Fingers of Death" freestyle rap challenge on SiriusXM's "Sway in the Morning" radio show.

"Get ready, get set, this a meme," LaBeouf began. "This is wild, this is a childhood dream." He then went on to rap for about five minutes, and he even labeled himself the "Jewish Pac," referencing the late, legendary artist Tupac Shakur.

Just watch the video above -- it will blow your mind!
