Henin-Hardenne is delighted after winning her semi-final.
"I played well on the big points," said third seed Henin-Hardenne, who now has the chance of completing her collection of Grand Slam titles.
The French Open champion lost her only Wimbledon final to Venus Williams in 2001.
"I love situations like this," added the 24-year-old, who has now won 13 consecutive Grand Slam matches without dropping a set.
