Conrad Murray Enjoys Trinidad Carnival Festivities with GF Nicole Alvarez

Conrad Murray -- Michael Jackson's former doctor who went to jail for his death -- is now enjoying the finer things in life ... like dancing with his hot girlfriend at Carnival.

Conrad was raised in Trinidad so he's reveled in the festivities before, and his longtime lady, Nicole Alvarez, was by his side.

Murray was convicted of involuntary manslaughter in 2011 and served 2 years, but still maintains his innocence ... telling us MJ's other docs were to blame.
