Mariah Carey became known for hitting all the notes at the beginning of her career, but RadarOnline.com has learned the temperamental diva can no longer sing her most famous early songs!
Carey, who recently kicked off her Sweet Sweet Fantasy Tour in Europe, has 17 songs on her concert set list, but her most famous and requested 1990 hit "Vision of Love" is conspicuously missing.
"She can't sing it or hit the high notes," an insider told Radar, adding she "can't lip synch the song either," since she recently got panned for her bad attempts while performing the song at Caesar's Palace in Las Vegas.
Video taken by fans last month appears to confirm her battle!
"The way she tries to match her hoarse warbling to the pre-recorded tracks, it looks like the bad dubbing in an old Japanese movie," laughed the insider.
And when Carey, who turns 46 on March 27, does actually sing, "It's a whispery Marilyn Monroe voice, or else she sounds like she's talking through the song," added the source.
Carey will head back to Las Vegas for her residency in June, and her current tour ends in Johannesburg, South Africa, on May 2.
Fans will likely continue to be disappointed that Carey's shows likely will not feature "Vision of Love" and few non-hip hop, straightforward ballads.
"It would be like Adele skipping 'Hello' or Celine Dion not doing 'My Heart Will Go On,'" blasted the insider.
