In September during the Toronto Film Festival they had a brief romance. Now Michael is intent on showing her he wants to get serious again and made a point of bringing his mum Adele to the Oscars rather than a date. “Lupita’s the most in-demand woman in the world at the moment so it will be hard to make it work but their chemistry is undeniable,” a source said. Fassbender was previously in a relationship with Gerard Butler’s ex-girlfriend Madalina Ghenea. PTI
