Top seed Justine Henin was in devastating form as she breezed past talented 5th seed Nicole Vaidisova 6-2 6-2.

"We will see what happens on grass in the future but you take a bit of time to get used to it. I grew up on clay but I have great qualities to play on grass.

"My game is getting better all the time. I trust myself on grass, but will it be good enough to win Wimbledon? I don't know."

3rd seed Nadia Petrova is also into the semis after a tough 3 set victory over 9th seed Sybille Bammer 6-7 7-5 6-4.

The final semi finalist is 2nd seed Amelie Mauresmo who defeated 6th seed Shahar Peer 6-3 6-4.
