Rihanna is a huge football fan, making headlines throughout the 2014 World Cup for her excited commentary on Twitter, and there were reports that she once had a brief relationship with Real Madrid striker Karim Benzema.
But now Mesut Ozil thinks she might well be Arsenal's lucky charm.
After full debutants Henrikh Mkhitaryan and Pierre-Emerick Aubameyang ran riot and Aaron Ramsey netted a hat-trick against the hapless Toffees, Ozil posted a selfie with Rihanna to his Twitter followers.
"Still unbeaten with Riri," Ozil wrote on Twitter, noting Rihanna had been present for Germany's win in the 2014 World Cup final.
Perhaps Arsenal should give her a season ticket.
The Gunners lie sixth in the Premier League table, four points from fourth place, which represents Champions League football next term.
