::::::I would ask, collegially, that  discuss rather than edit-war.  
 *Removing two print citations because they are not online is improper; are you saying Wikipedia can never cite print sources?  
 *The Indepndent did mention the alternate name, spelling it "Demitria".  
 *The snarky, non-neutral WP:TONE taken in regards to People magazine — a reputable Time Inc. publication with scores of staff and fact-checkers — shows a slanted and a bias, both of which are improper per WP:NPOV.  
 *Moore's tweet is the very first footnote, giving it primacy without undue weight. 
 *And issues of birth name go in the lead, per consistency across the vast bulk of Wikipedia. 

 ::::::At least one other editor disagrees with 's unilateral, summary ownership. Compromises can be tweaked, obviously, but to overhaul it in slanted way while removing print citations is not right. Let's discuss this rather than call in mediation or an admin over the OWN issue.
