Terrell Owens Says You Can't Open His Package Til Christmas

Talk about a yule log I'd like to deck my walls.  What we really wanna know is who is the guy taking the pics?  Terrell Owens is clearly not skipping ab day since retiring because he still looks great. 

T.O.'s 45-years-old now and hasn't played ball in years -- but the guy's obviously been keepin' himself in shape ... check out the pics he posted in front of his Christmas tree!!!

Unclear why Owens felt the need to post the pics ... but the tiny gift-themed shorts and the caption seem to suggest this was T.O.'s present to us all.

"Do Not Open Package Til Christmas," he wrote.
