Emma Raducanu for Tiffany

U.S. Open tennis champion Emma Raducanu adjusts an earring in this public relations photo from Tiffany & Co. Raducanu became a paid ambassador for the brand in September of 2021, a few weeks after she was the surprise winner of America's most prominent tennis tournament. Emma Raducanu was born on November 13, 2002, so she was still only 18 when she won the tournament and signed her sponsorship deal.
