Ronaiah Tuiasosopo got a visit from a world famous psychiatrist last night ... a guy who's worked with everyone from Michael Jackson to Paris Hilton ... TMZ has learned.
The shrink to the stars is Dr. Charles Sophy -- a high-ranking official with the Los Angeles Dept. of Children and Family Services.
Sophy was involved in the Michael Jackson child molestation case, the Paris Hilton jail saga (when she was suffering from panic attacks) and counseled Taylor Armstrong during her split with her husband.
But last night, Sophy appeared at the Tuiasosopo family home in Palmdale, CA ... and though he wouldn't say why he was there, it's obvious his visit is connected to the drama surrounding the Manti Te'o hoax.
When we asked Dr. Sophy if his visit was in connection to a TV show -- the doc told us, "You know I can't discuss anything."
As for Ronaiah, he has yet to speak to the media about the hoax -- but Manti says he's already called him privately and confessed to everything.
