Prince: Remembering him on his birthday

(CNN)Tuesday was supposed to be a day of celebration for Prince fans.

But with an ongoing investigation into the death of the pop icon, the stage has also been set for it to be a day of mourning.
The star, who died on April 21 at age 57, was remembered on social media, radio stations and around the world with more than a few wishing he was still here to share in the accolades.
    The Saturday before Prince's birthday, director Spike Lee threw a party in Brooklyn in honor of his friend. There was plenty of dancing, performances and celeb sightings. Naturally the color theme was purple.
