Pitbull's not getting out of Lindsay Lohan's legal doghouse -- because she's blowing off his apology for using her name in a song ... and rejecting his invitation to the MTV VMAs.
On Wednesday, Pitbull taped an apology (below) ... claiming he meant no harm, and invited Lindsay to join him at the VMAs this weekend -- where he's scheduled to perform the song.
Sources close to Lindsay tell us she has no interest in going to the VMAs -- and Pitbull's apology has no impact on the lawsuit ... it's moving forward.
