Formula One driver Nico Rosberg has revealed he wears a woman's sanitary towel on his head during racing.
Rosberg, Lewis Hamilton's team-mate at Mercedes, said he has started putting the 'sort of headband' inside his helmet to stop sweat trickling down his eye while driving.
Rosberg currently trails team-mate Hamilton by seven points in the championship.
Sebastian Vettel has knocked back an invitation from Nico Rosberg to visit the Mercedes garage this weekend, fearing a PR stunt.
Rosberg and Vettel became involved in a spat during the post-Australian Grand Prix press conference which resulted in the Ferrari driver suggesting Mercedes should open up their garage at the Sepang International Circuit for an inspection of their cars in the wake of a dominant display at Melbourne's Albert Park.
Rosberg then invited Vettel, with the latter suggesting the debrief in the engineers' room for his visit.
Vettel has now knocked back any chance of a visit: "When I was joking with Nico in the press conference the deal was the invite was for all the paddock. Now it seems the invite has shrunk to just me.
"Initially I think it was called off by Niki (Lauda, Mercedes non-executive director) and Toto (Wolff, Mercedes motorsport boss).
"Now they've told (Rosberg) yes, so I think they are using it as a bit more of a PR thing rather than a proper invite, so the answer is no I won't be going."
Formula One team Mercedes has disciplined Nico Rosberg for crashing into team-mate Lewis Hamilton during last weekend's Belgian Grand Prix, warning the German driver that "another such incident will not be tolerated."
The team said Rosberg has "acknowledged his responsibility for the contact" that occurred in the second lap of Sunday's race and "apologized for this error of judgment."
Mercedes says "suitable disciplinary measures have been taken" against Rosberg but that he is free to race in the championship.
Rosberg leads the drivers' standings on 220 points, with Hamilton in second place on 191.
Mercedes says the two drivers "accept the team's No. 1 rule: there must be no contact between the team's cars on track."
