Shelly Sterling PHOTOBOMBED by 'Famous in 12' Girls [VIDEO]

Shelly Sterling was full-on mobbed by paparazzi as she left Craig's restaurant in West Hollywood Tuesday night ... and she was also epically photobombed by the girls from "Famous in 12."

Shelly has been low-profile since inking a deal last week to sell the L.A. Clippers. So it was a feeding frenzy outside the restaurant when Jameelah, Taliah and Maariyah Artiaga latched onto her like moths to a flame ... and it's hilarious.

The girls are part of a TMZ social experiment ... we moved their family to L.A. from a small town and we're giving them 12 weeks to scheme their way to fame. The show airs Tuesdays on the CW at 8 PM.

So far ... crazy.
