Mexican-American singer Jenni Rivera, who sold over 15 million albums worldwide and recently won two Billboard Mexican Music Awards, died yesterday in a plane crash in the mountains of northern Mexico. She was 43 years old.

The plane went missing around at 3:40am departing from the city of Monterrey, where she had just performed in front of thousands of fans. The small plane only had six other passengers on board, all of whom are also reported to be dead -- her publicist, her lawyer, a family friend and two pilots. Authorities have not officially confirmed her death, but there are few doubts she was on the plane that disintegrated on impact.

Her death came as Jenni was arguably reaching the peak of her career as the biggest singer in grupero, a male-dominated regional style. Her 2008 album Jenni reached No. 1 on the U.S. Top Latin Albums chart and her 2009 album La Gran Senora reached No. 2. She was also nominated for Latin Grammys in 2002, 2008 and 2011. In addition, she was gearing up to take over the English language market after gaining immense success with her reality show I Love Jenni, which was currently shooting its third season. She had a deal with ABC to star in a sitcom pilot called Jenni.

"We lost an awesome woman, mother, sister, friend and artist," said her business partner and manager Pete Salgado. Rivera is survived by her five children and two grandchildren.

Our deepest condolences go out to her family and friends at this time.
