Wait 'til you see Chris Pratt at 13, almost unrecognisable, but just as cute. The latest #phenomenon swirling through the twittersphere (thanks to a CNN special which aired last night, focussing on "the secret lives of teens) involves celebrities dutifully posting photos of them #Being13. They mostly fall into two categories - you have those who look about 23 aged 13 (Angelica Houston and Cher)

and then you have the boys... although Wyclef Jean's suit does add to his years. 

The lovely Anna Faris also got involved...

These were indeed more innocent, less self-absorbed times. Nowadays we have 13-year-old's taking over 100 selfies before committing to posting the right one... 

 
One word - frightening.
