Justin Bieber is having the last laugh.
Mariah Yeater, 20, made headlines last fall when she claimed Bieber was the father of her baby and the singer is only just now laughing about it.
Bieber, 18, tweeted on Saturday, "Dear mariah yeeter…we have never met…so from the heart i just wanted to say…" He then linked to a YouTube clip of Sacha Baron Cohen's Borat character repeating, "You will never get this. You will never get this. La la la la la…"
Yeater claimed in late October of last year that she became pregnant with Bieber's baby after a sexual encounter backstage his concert at the Staples Center in L.A. when she was 19 and Bieber was 16.
The "baby" singer said he had never met Yeater and reportedly took a DNA test to prove her wrong.
Yeater withdrew her lawsuit and Bieber's team said in a statement they would, "vigorously pursue all available legal remedies to protect Justin and hold those involved with bring this suit accountable for their actions."
The tweet Bieber addressed to Yeater (though he spelled her name wrong) was part of his "Random Twitter Hour" on Saturday. He tweeted anything and everything that came to mind including, "Kinda weirded out that no one got the secret meaning of #boyfriend Obviously listening closely you can tell its about the migration of birds."
