British Formula One driver Jenson Button and his long-term model girlfriend Jessica Michibata have become engaged.
The Japanese-born Michibata could be seen sporting a diamond engagement ring as she kept tabs on her fiance during Thursday's pre-season testing at Bahrain's Sakhir circuit.
McLaren posted a message on their twitter page saying: "Huge congrats to @JensonButton and @jessybondgirl on their engagement! #attaboy".
And Button's new teammate, Kevin Magnussen tweeted: "Wow! Well done to @JensonButton & @jessybondgirl on your engagement!"
The pair met over five years ago with Button, whose father John died suddenly of a heart attack aged 70 in January, telling the BBC that he had proposed on Valentine's Day.
Michibita, whose mother is Japanese and father half-Spanish, was born in Fukui near Kyoto.
