PARIS, June 9 (Xinhua) -- World number one Justine Henin won her third consecutive title and fourth in total at the French open as she thrashed the seventh seeded Serb Ana Ivanovic in a one-sided final on Saturday.

The top seed, who racked up her three titles in 2003, 2005 and 2006 before this year's edition, was in a class of her own overwhelming the 19-year-old youngster 6-1, 6-2 in just one hour and 5 minutes despite a nervy start in the first set.

The 25-year-old Belgian completed a rare title hat-trick since Monica Seles' registration of three consecutive French Open crowns achieved in 1990-1992.

Appearing in the first Grand Slam final of her young career, Ivanovic just posed challenge towards Henin in the first two games of the match and struggled poorly throughout the remaining time, making 31 unforced errors to 14 of Henin and five double faults to just one of her opponent.

But she still felt happy enough as the promising star was the first player representing Serbia to feature in the final of a grand slam tournament.

"There will be more finals," the Serb said in a courtside interview. "I started perfectly but then I became nervous and I was just unable to control my serve game. What can I say, she's an amazing player."

Back at her best after the breakdown of her marriage and her subsequent withdrawal from this year's Australian Open, Henin looked far too strong for Ivanovic, who crushed Russia's world number two Maria Sharapova in the semi-finals and number three Svetlana Kuznetsova in quarterfinals.

"I was a little bit of nervous at the beginning of the match but then everything went well," said Henin, who sealed the comfortable victory with a forehand volley on the first match point.

"I've been through difficult moments at the start of the year but I fought to get over them and now I'm really enjoying myself again.

"When I was a little girl, I never dreamed this would happen tome, " she talked of her title hat-trick.

Opening with a sluggish start, Henin was forced to save two break points in her first service game, but a double fault following an unforced error assured her opponent the service break.

However, the never-give-up Belgian drew blood immediately, cracking back with the help of some lucky moment when the ball hit the cord and rolled down onto Ivanovic's side of the court.

Then the Belgian stayed on top and reeled off the 11 of the next 13 games to take the win at 6-1, 6-2 and extend her reign as the queen of the Paris clay court tournament.
