Dealing with sexual assault allegations and a lawsuit, X-Men: Days of Future Past director Bryan Singer has dropped out of a May 2 "Creativity Conference."

According to a source who spoke exclusively with The Hollywood Reporter, Singer dropped out of the conference, which is co-sponsored by the Motion Picture Association of America, ABC News and Microsoft.

Vice-President Joe Biden is also expected to make an appearance. The "Creativity Conference" is just one of the events that happen alongside the White House Correspondent's Dinner in Washington, D.C.

With the allegations floating overhead, Singer's involvement in projects is starting to make procuders tread lightly, wary of even using his name. On Thursday it was discovered that promos for ABC's upcoming drama series Black Box containing his name were yanked from circulation. He served as an executive producer on the straight-to-series drama.

Should the lawsuit continue forward over the next few months, Singer's name might not also be included in promotion of CBS' Battle Creek, which he directed the pilot episode.

As previously reported, Michael Egan filed a lawsuit against the director claiming sexual assault when he was underage and looking to land a role in the first X-Men film.

He claims that Singer took him to a mansion for a party where it was quietly known to often involve "sexual contact between adult males and the many teenage boys who were present."

Egan says that in 2000 after the alleged sexual assault, he tried to go to the Los Angeles Police Department and the FBI, but nothing ever happened and charges were never filed.
