Miley Cyrus & Justin Bieber’s Moms — Power Lunch in L.A.

It was a meeting of the power moms — Miley Cyrus and Justin Bieber“s mothers on a lunch date in L.A. today … and Justin”s mother was an OPEN BOOK.

We can only imagine what they talked about — money, money, and more money — but one thing”s for sure, Bieber”s  old lady Pattie Mallette didn”t hesitate to pass along a copy of her new autobiography “Nowhere But Up.” (Foreword by Justin Bieber … of course)

Tish Cyrus left the cafe with a conveniently-posed copy of the book tucked under her arms.

As for other interesting talking points — Tish said there”s still no date for Miley”s wedding to fiance Liam Hemsworth.
