Ons Jabeur produced a superb comeback to beat Aryna Sabalenka and set up a Wimbledon women's singles final against unseeded Czech Marketa Vondrousova.
Jabeur's hopes were slipping away at a set and 4-2 behind but she rode a wave of momentum and raucous support to win 6-7 (5-7) 6-4 6-3 and reach a second successive final at the Championships.
It means there will be a new Wimbledon and Grand Slam champion on Saturday.
Vondrousova ended Ukrainian Elina Svitolina's run by winning 6-3 6-3.
She is the first unseeded player to reach the Wimbledon women's singles final in the Open era.
