On Saturday night, Rivera had given a concert before thousands of fans in Monterrey. After the concert she gave a press conference during which she spoke of her emotional state following her recent divorce from former Major League Baseball pitcher Esteban Loaiza, who played for teams including the New York Yankees and Los Angeles Dodgers.
"I can't get caught up in the negative because that destroys you. Perhaps trying to move away from my problems and focus on the positive is the best I can do. I am a woman like any other and ugly things happen to me like any other woman," she said Saturday night. "The number of times I have fallen down is the number of times I have gotten up."
Rivera had announced in October that she was divorcing Loaiza after two years of marriage.
There have been several high-profile crashes involving Learjets, known as swift, longer-distance passenger aircraft popular with corporate executives, entertainers and government officials.
A Learjet carrying pro-golfer Payne Stewart and five others crashed in northeastern South Dakota in 1999. Investigators said the plane lost cabin pressure and all on board died after losing consciousness for lack of oxygen. The aircraft flew for several hours on autopilot before running out of fuel and crashing in a corn field.
Former Blink 182 drummer Travis Barker was severely injured in a 2008 Learjet crash in South Carolina that killed four people.
That same year, a Learjet slammed into rush-hour traffic in a posh Mexico City neighborhood, killing Mexico's No. 2 government official, Interior Secretary Juan Camilo Mourino, and eight others on the plane, plus five people on the ground.
