France set up a Women's Six Nations title decider against England by crushing Wales 40-0 in Cardiff on Sunday.
The French ran in six tries to ensure a dramatic conclusion to the tournament in Bordeaux next weekend.
England sit top of the table on 20 points after thrashing Ireland 88-10 on Saturday, with France one point behind in second place.
Both England and France have won all four of their matches, while winless Wales sit bottom of the table.
France had debutant Anne-Cecile Ciofani sent to the sin bin for a first-minute tackle on Hannah Jones.
Despite the numerical disadvantage, the French raced into a 14-0 lead inside 18 minutes.
Annaelle Deshayes and Joanna Grisez touched down and Lina Queyroi added the conversions.
Romane Menager's try made it 19-0 at the break before tries from Gabrielle Vernier and Manae Feleu, plus two more Queyroi conversions, stretched the lead.
Assia Khalfaoui was shown a yellow card for a head-on-head challenge on fly-half Lleucu George.
But Grisez claimed her second try of the game after she pounced on Cath Richards' loose pass inside her own 22 with Morgane Bourgeois converting to complete the rout.
