WATCH LIVE: Jenni Rivera memorial and 'celestial graduation'

Fans of Jenni Rivera flocked to Universal City Walk on Wednesday morning to attend a public memorial for the singer. The "Celestial Graduation" begins at 10 a.m. and ends at noon. 

Free tickets to the venue, which can hold more than 6,100 people, were sold out minutes after they were made available this week.

"We will celebrate the graduation into heaven, with honors, of our beloved mother, daughter and sister Jenni Rivera," the family said in a statement.

Many fans brought handmade posters and white roses to commemorate the star. Rivera's children asked that donations to the Jenni Rivera Love Foundation be made in lieu of flowers, in addition to a single white rose.

The Mexican American banda singer and six other people were killed Dec. 9 when a Learjet 25 crashed near Iturbide, Mexico. Though an investigation into the crash is ongoing, Mexican authorities have told reporters that they believe her plane dropped 28,000 feet at speeds that might have exceeded 600 mph.
