What did Maria give Henrik as he was exiting the limo?

She despised him because of their history and spent the whole night being bitchy to him, then when he got out of the car, after she laughed in his face when he invited her in for a nightcap, she wrote something on a scrap of paper and handed it to him. It was her phone number, right? I didn't fully catch it visually. But she was doing it to lead him on just so she could be extra cruel to him later if he actually called her and claim she was too drunk to know what she was doing. Or am I missing something?
