Superstar Jenni Rivera's LA memorial set for Wednesday

Tickets to Jenni Rivera's memorial Wednesday in Los Angeles, an event her family calls her 'graduation into heaven,' were snapped up the day before.

LOS ANGELES — Fans and family members of Jenni Rivera were set to celebrate the life of the banda singer Wednesday at a Los Angeles memorial service after she was killed in a plane crash in Mexico.

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

Free tickets to the public memorial service were quickly snapped up Tuesday. Rivera's burial will be private.

The 43-year-old Rivera and six others died Dec. 9. The crash remains under investigation.

Rivera sold more than 15 million copies of her 12 major-label albums. Her soulful singing style and her honesty about her tumultuous personal life won her fans on both sides of the U.S.-Mexico border. She was also an actress and reality-TV star.

Born in Los Angeles, Rivera launched her career by selling cassette tapes at local flea markets. By the end of the 90s, she won a major-label contract and built a loyal following that knew her as the "Diva de la Banda."

Many of her songs deal with themes of dignity in the face of heartbreak.
