Alleged Bryan Singer Victim -- Lawyer Says This is What My Client Looked Like

The lawyer for the man who is suing "X-Men" director Bryan Singer has given us this picture of his client -- taken around the time Singer allegedly drugged and sexually abused the then 17-year-old.

Attorney Jeff Herman gave TMZ this photo of his client, Mike Egan ... a photo taken when Egan was 17. Herman wanted to make the point ... Egan looked underage when he went to Hawaii with Singer on a trip in which the director allegedly anally raped Egan multiple times ... so he claims in the lawsuit.

Herman tells TMZ ... Egan will be present at a news conference today at 2 PM PDT where he will discuss his allegations.

As we previously reported ... Egan claims he encountered Singer numerous times ... the first of which was at a gay party in Encino, CA where Singer allegedly forced Egan -- who was 14 or 15 at the time -- to perform oral sex on him underwater in a pool.

Egan says in the lawsuit he is heterosexual.

Singer's lawyer, Marty Singer, tells TMZ the allegations are utterly false and publicity driven.
