Despite a dramatic tabloid report this week that she collapsed at her English estate because she was weakened by an extreme diet, the musician's rep insists she's in excellent health.
"It is absolutely and completely untrue," Presley's rep tells PEOPLE of claims that Presley was rushed back to the United States for treatment by the Church of Scientology after losing 55 lbs. in five months. "The National Enquirer puts Lisa on the cover every few months with manipulated photos and horrendous stories of supposed 'meltdowns,' and has since she can remember."
Presley, 42, is Los Angeles for work, recording her third album.
"She is happy and healthy and working hard," adds the rep. "The rest is absolute garbage. Not a bit of truth to any of it."
Presley's main residence is in England, where she lives with her guitarist husband Michael Lockwood. She has four children.
