Donald Sterling Wife Busted Him With V Stiviano – She Must Got That Fire

Donald Sterling and V. Stiviano reunited at his Beverly Hills mansion today — and when Donald’s wife found out … she called police, trying to get V. arrested … TMZ has learned.

We’re told Shelly Sterling got wind of Donald and V.’s tryst … and believed Stiviano must have broken into the house. Our Sterling sources tell us Shelly called Bev Hills PD immediately and reported a break-in.

We’re told police officers responded … and spoke to Donald and Stiviano. One source tells us V. was an “invited” guest, so … no break-in, and no arrests. 

Shelly has beef with V. … She sued the alleged mistress, claiming she embezzled $1.8 mil from Donald … and Shelly says half of that was hers.  Shelly claims V. swindled an old man who wasn’t with it.

Cops tell us V. wasn’t scared off … she stayed after they left.
