Two-time Wimbledon champion and world number seven Petra Kvitova has been confirmed to play at the Aegon International in Eastbourne in June.
Kvitova, 26, and defending champion Belinda Bencic will compete at the pre-Wimbledon tournament.
Bencic, 19, defeated Agnieszka Radwanska in the 2015 final and is currently ranked 10th in the world.
"I think it's the best preparation for Wimbledon and I have some fun memories there," Kvitova said.
The tournament at Devonshire Park takes place the week before Wimbledon from 18-25 June.
