Harry Styles may have splashed out more than half a million dollars on new fiancée Zoë Kravitz's engagement ring, according to new claims, Wonderwall.com can report. Engagement rumors began swirling after the Big Little Lies star wore an enormous diamond sparkler while out and about in London and New York City in recent days.
