They were first spotted dining in London together two weeks ago, sparking reports that they were rekindling their relationship.
And now there is no doubt that Jenson Button and Jessica Michibata are an item once again.
After confirmation of their reunion last week, the couple were seen walking around Budapest hand-in-hand ahead of Jenson's race there on Sunday.
Jenson and Jessica, 25, announced the end of their 18-month relationship back in May, citing long distance as the cause.
But last week the Monaco-based driver confirmed they were an item again, saying: "Jessica will be with me for the Hungarian Grand Prix next weekend. We are back together."
Writing on her Twitter page this week, Jessica wrote: "Nice weather in Hungary! Catching up with everyone. So good to be here."
She also posted a photo of her with Jenson, 30, and his McLaren teammate Lewis Hamilton, pictured.
