Easter Egg(Mary Magdalene)

I was researching the easter egg and i found on wikipedia (http://en.wikipedia.org/wiki/Mary_Magdalene) this article. I was wondering if it is correct. Easter Egg tradition For centuries, it has been the custom of many Christians to share dyed and painted eggs, particularly on Easter Sunday. The eggs represent new life, and Christ bursting forth from the tomb. Among Eastern Orthodox this sharing is accompanied by the proclamation “Christ is risen!”.
One tradition concerning Mary Magdalene says that following the death and resurrection of Jesus, she used her position to gain an invitation to a banquet given by Emperor Tiberius Caesar. When she met him, she held a plain egg in her hand and exclaimed “Christ is risen!” Caesar laughed, and said that Christ rising from the dead was as likely as the egg in her hand turning red while she held it. Before he finished speaking, the egg in her hand turned a bright red, and she continued proclaiming the Gospel to the entire imperial house.

There is also a supposed tradition that the remnants of Christ’s heart remain inside an egg-like vessel, and that this vessel is the basis for “the Sacred Heart” motif in Catholicism. In some legends the Sacred Heart exists as a guarded sacred object or a metaphysical essence, passed from hand to hand, with Mary Magdalene being listed among noteworthy caretakers.

The part I was wondering if it was correct was mainly the part about mary and the egg(it turning red infront of Ceaser. If the article is not correct i would appreciate it if you could explane why we have the easter bunny and easter eggs on easter.
