She's an ex-Facts of Life star, the voice of Velma in several Scooby-Doo! projects — and the godmother of Brangelina’s kids?!

The new Us Weekly reports that ’80s sitcom star Mindy Cohn was recently heard bragging that Brad Pitt, 46, and Angelina Jolie, 35, chose her to be the godmother of two of their six children!

“Mindy is good friends with them,” the insider tells Us Weekly. “They even gave her a huge diamond ring to thank her for being the godmother.”

(Though the insider says Cohn, 44, didn’t say which kids she is responsible for, the single actress was first photographed sporting a huge rock in September 2008, two months after twins Knox and Vivienne, now 2, were born.)

Jolie’s brother, James Haven, 37, is apparently also a friend of the spunky star. The pals posed together at the L.A. Fast Food Nation ­premiere back in 2006!
