British number one Katie Boulter and former US Open champion Emma Raducanu will compete in a historic women's tournament at Queen's Club in June.
Australian Open champion Madison Keys, two-time Grand Slam champion Naomi Osaka and last year's Eastbourne champion Daria Kasatkina have also committed to the event, which runs between 7-15 June.
It will be the first women's competition at Queen's Club since 1973 when Olga Morozova claimed the singles title.
"I used to watch the [men's] tournament every year growing up so to be able to compete at such a wonderful, historic, and iconic event to commence the grass court season is an honour," Boulter said.
