Alex Pettyfer plays an alien in the upcoming flick "I Am Number Four" -- and his abs are definitely out of this world!
The 20-year-old actor, who is dating "I Am Number Four" and "Glee" star Dianna Agron, went for a shirtless jog this weekend in L.A. -- where he showed off his seriously toned and tattooed body.
Besides the cross on his chest, Pettyfer also has Arabic writing on his right arm, the words "What Goes Around Comes Around" on his shoulder and the letters "ER" on his right wrist. "ER" are the initials of ex-girlfriend Emma Roberts.
"I Am Number Four" opens February 18. Click the gallery for more shirtless studs!
