Janet Jackson's song "Make Me" from her newly-released album Number Ones is making sources close to Janet and her late brother's estate clash.

The debate centers around a lyric that reads, "Don't stop till you get it up." A source told ET that Michael's estate questioned Janet's right to use the lyric because of its similarity to his song "Don't Stop 'Til You Get Enough," featured on Michael's album Off the Wall.

Now a source close to Jackson estate special administrators John Branca and John McClain tells ET, "There is no war and it's ridiculous to suggest it." Estate representatives have made no official comment, nor have we reached Janet Jackson's representative so far.

The Jackson family has clashed with Michael's estate previously. Back in August, family matriarch Katherine Jackson was allowed to challenge Branca and McClain without risk of jeopardizing her position as a beneficiary in his will.

And just earlier this month, Katherine withdrew her objection to Branca and McClain being the administrators of the will, while patriarch Joe Jackson filed a motion claiming that the lawyers have a "conflict of interest" and should be removed as administrators of the late singer's will.
