The woman who claimed to be Justin Bieber's baby mama is running for the hills, because we've learned neither she nor her lawyer have made ANY attempt to contact Justin's team ... to compare his DNA with her baby's.
We broke the story ... Justin took a DNA test in New Jersey last Friday, and sources connected with the singer say he's chomping at the bit ... waiting for Mariah Yeater to ante up her baby's DNA results. But so far ... crickets.
Yeater's lawyer has been blabbing to the media, but has stayed clear of anyone in Justin's camp. Sources connected with Justin believe Yeater will never produce DNA results, because it will simply become ammunition for a lawsuit he intends to file against her and her lawyers for abuse of legal process.
