The entertainment world is on tenterhooks after the appearance of new images that suggest Harry Styles and Zoe Kravitz may have taken the next step in their relationship. Engagement rumors intensified on Tuesday after Kravitz was photographed sporting a striking diamond ring on her ring finger during an outing in New York City. The couple, who have maintained a relatively low profile since they were first romantically linked in August 2015, were seen strolling through the streets of New York City looking relaxed yet affectionate. However, what caught the paparazzi's attention was the oversized jewel that the actress and director made no attempt to conceal. Sources close to the couple told outlets such as Page Six that the relationship between the "As It Was" singer and Lenny Kravitz's daughter has progressed rapidly. "Harry doesn't usually go public with his relationships unless they're very serious," commented an insider. In fact, insiders claim that Kravitz already refers to Styles as her "soulmate" among her closest friends. The romance began to solidify after several romantic trips to Rome and London, and more recently, a "special" trip to the Bahamas where, according to rumors, the proposal may have taken place. This possible engagement comes at a time of great exposure for both. While Styles has just released his fourth studio album, Kiss All The Time, Disco, Occasionally, and is preparing for a residency at Madison Square Garden, Kravitz continues to achieve success in her role as a director. So far, representatives for both artists have declined to make official comments, maintaining the aura of mystery that has always surrounded their romance.
