Happy Birthday, Mario Lopez!
The X Factor host celebrated the big 4-0 on Thursday, Oct. 10, giving fans a great glimpse from his past: a pic of himself when he was a little guy!
"Going way back for #TBT almost 40 yrs ago... Here's my little fat self back in the day #Gordo," Lopez tweeted along with the chubby baby photo.
The black and white old-school pic shows a very smiley Lopez, with lots of thick hair and a huge grin. By the looks of it, he is only wearing a diaper for this photo shoot.
