Bezos and his ex-wife, MacKenzie Scott, with whom he shares four children,split officiallythat same year. Sánchez was already in the process of divorcing her husband, Patrick Whitesell, with whom she shares two children. In a post to theblogging website Medium in February 2019,Bezos accused the National Enquirer of blackmailing him with intimate text messages and photos he and Sánchez exchanged, several of which, the outlet claimed, showed him still with his wedding ring on. "Of course I don't want personal photos published, but I also won't participate in their well-known practice of blackmail, political favors, political attacks, and corruption," Bezos wrote in the post.

The first year of their romance was marked by a slow ramp-up of public appearances, contrasted heavily with their current, more saturated presence in the public eye. In 2020, the pair jetted off to India for a trip to the Taj Mahal and several public engagements. For one of the world's leading businessmen, public appearances are often varied and high-powered. As their romance heated up, Sánchez became a familiar figure on his arm not just during personal outings, but during business ventures as well.
