Although she was attending in a working capacity, it has stoked rumours that Vettel could be eyeing the world famous endurance race in the future.
The four-time F1 champion retired at the end of last year but could be tempted back in by an opportunity to participate in such a prestigious event.
Roeske was Vettel’s press officer for more than a decade at Red Bull, Ferrari and Aston Martin.
She exited F1 at the same time as Vettel did, but appears to retain a working capacity alongside him.
Roeske was working as a journalist on French TV at Le Mans.
But she was also spotted in the garage of Porsche, the iconic German manufacturer.
It will set tongues wagging that Vettel has a direct line of communication with the team from his home country.
Now 35, a route back into racing could be at a future Le Mans event.
