Reigning champion Donna Vekic will join British number one Johanna Konta at the Nottingham Open this summer.
The Croatian world number 50 caused an upset by recovering from a set down to beat the home favourite in the 2017 final at the Nottingham Tennis Centre.
"I'm so excited to be returning," said Vekic, 21. "It was such an incredible feeling to win the event."
The Nottingham Open takes place from 9-17 June with a combined tournament for men and women.
Tournament director, Rebecca James, said having both of last season's women's finalists for the pre-Wimbledon event was "great news".
