This is weird. I thought it was Mary Magdalene who washed His feet.
Luke 8:2 And certain women, which had been healed of evil spirits and infirmities, Mary called Magdalene, out of whom went seven devils.
John 11:2 It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.
2 different Marys. Both showing reverence.
