England Women became the first women's team to win four Six Nations titles in a row as they thrashed Scotland 72-3 at London Welsh RFC to retain their crown.
Worcester wing Katherine Merchant grabbed four of their 12 tries in all, with Saracens' Charlotte Barras weighing in with a hat-trick.
Only a one-point defeat by Wales saw England miss out on another Grand Slam.
"This was a tremendous way to end the championship. It's a marvellous achievement," said coach Gary Street.
"Our defeat against Wales was real motivation for us to pick ourselves up and prove what we can do. Even though we haven't won the Grand Slam, this has been our best Six Nations championship in my opinion."
"I'm already focusing on the year ahead which includes the Rugby World Cup in 2010. To be honest, I can't wait for our next game now."
Wales won the Women's Triple Crown by beating Ireland 13-10.
