The entity Jeremiah was mocking was Ashtoreth or Astarte. She, if she exists, is not in heaven.
The Mother of the Lord is very much in heaven. She is a Queen (the Hebrew term is "gebirah", great lady) because she is the Mother of the King. (Martin Luther agreed with me on that.)
He had told a crowd of some 100,000 people packed in rain-soaked St. Peters Square just after his election that he intended to pray to the Madonna that she may watch over all of Rome.
You shall not make for yourself a carved imageany likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My commandments. Exodus 20:4-6
