L-A Radio: Dani Mathers Lawyers Up

Dani Mathers, who was the 2015 Playboy Playmate of the Year and was suspended from her frequent hosting spot on the "Heidi and Frank" show on KLOS 95.5 FM has lawyered up.

TMZ reports Mathers hired Tom Mesereau, who not only got MJ off ... he won a murder acquittal for Robert Blake.

TMZ broke the story, the LAPD launched a criminal investigation after the gym where the photo was taken filed a police report. Mathers not only snapped the pic in the locker area, she shamed the woman by writing a snarky caption and posting it on social media.

LAPD sources say they are on the hunt for the victim and are working closely with LA Fitness execs, combing over surveillance video and checking member swipes during the time in question to ID the victim.

Our sources say the LAPD would like to present a criminal case to the L.A. City Attorney but need the cooperation of the victim.
