Congratulations to Jenson Button and Jessica Michibata - the latest celeb couple to enter the white zone!
The Formula One champ proposed to his model girlfriend of five years with a dazzler of a ring.
A spokesperson for Jenson formally confirmed the news and said the happy couple were 'delighted'.
Jessica was spotted in the paddock of the Formula One Winter Testing in Bahrain this morning, happily showing off her new bling. The (huge) rock is rather special: a teardrop diamond with a platinum or white gold setting.
They first started dating in 2008, after meeting in a hotel bar in Tokyo. Jessica turned Jenson down to begin with because she thought he was a bit of a womanizer, but caved in eight months later.
