Pete, Ashlee 'n Bump Make Three

Newlyweds and parents-to-be Ashlee Simpson and Pete Wentz prepare to depart from LAX international airport on Sunday.

Even more interesting is the security guard in the background looking into the camera with his pleading eyes.

It's as if he's trying to tell us something...

Tired Old Guard: Help me! I have lost my ability to speak, but I am hoping that by reading my eye movement, you can decipher that I am trying to tell you that Pete is, in fact, NOT the baby's daddy. Ashlee and I experienced a brief indiscretion after she came off a flight a few months back... She was hopped up on Cola and Gummy Bears and feeling rather vulnerable because her luggage had been lost. As I was helping her in my office, our eyes locked, and she had her way with me. Afterward, she never called. Why... WHY!? I have a right to father MY child!

Poor dude.
