Button and Louise to tie the knot.

BAR Honda driver Jenson Button is to marry girlfriend and Fame Academy star Louise Griffiths.

Button, according to reports by New magazine, proposed to her during a recent holiday at the luxury Sandy Lane Hotel, Barbados.

One of the Button's friends told the magazine: "He arranged an appropriate dinner at the hotel and asked Louise to marry him.

"It came as a complete surprise to her and she accepted.

"Jenson then presented her with an engagement ring. They're a very strong couple and very happy."

The announcement follows Louise's stint in Fame Academy, where she declared he was the 'love of my life'.

Although no details have been released of when or where the couple will finally tie the knot, it is possible that the ceremony will take place sometime next year - maybe before the first race in Australia in March, or more likely following the final race in Brazil on October 24.
