Pop veteran Cher will replace Celine Dion at Caesar's Palace in Las Vegas, Nevada, in two years' time.
The If I Could Turn Back Time singer, who recently completed her Farewell Tour, will take up residence in the gambling mecca in 2008.
Caesars Palace is planning to build a unique concert hall to house Cher's extravagant show.
The 38-year-old was struck down with labyrinthitis - an inflammation of the inner ear causing dizziness.
Dion said she refused to take medication after learning it could dry out her vocal chords but added she was now "95% better".
Dion's show, A New Day, opened at Caesars Palace in March 2003.
Charity show
She decided to "take a chance" and return to the show after a doctor said jittery movements in her eyes had stopped.
"It's hard to do a show, but it's harder not to do it," Dion said.
"When you come back, you're afraid. You're scared and you're like, kind of ashamed.
"Then you talk to yourself and say, 'You're a human being, it can happen'."
Dion will perform her 500th show at Caesars Palace on Sunday, which will raise $1m (£541,436) for 10 local charities.
The performer said she is excited about the show, with some concertgoers paying up to $10,000 (£5,414) for two front-row seats.
She said: "It's amazing that people wanted to come and make a difference, too. It's rewarding. It's wonderful."
Dion's run at the 4,100 seat theatre is due to run until the end of 2007.
Singer Forced To Cancel Vegas Shows
Celine Dion has ear troubles.
Dion is suffering from a rare ear disease called labyrinthitis.
Dion had to cancel almost a week of shows.
She's been telling fans her condition could last from a couple of weeks to a year.
Her husband and manager, Rene Angelil, said it began with a viral illness.
Angelis said Dion suffered from severe vertigo caused by fluid in the inner ear.
A Quebec native, Dion is a Grammy- and Oscar-winning singer.
In 2003, she began three-year commitment to perform in an arena built for her in Las Vegas.
She was born to a catholic family in the small town of Charlemagne, Quebec, with a singing voice that her mother encouraged. By the age of five she was performing for anyone who would listen.
In 1980 her mother brought her to agent/manager René Angélil, who so believed in her voice that he mortgaged his home to help finance her career. In 1981 they released her first record in her native French language, 'La Voix du bon Dieu' ('The Voice of God'), which made her an instant star in Quebec. The following year she competed and won the gold medal at the Tokyo World Song Festival. Her career continued to blossom, and in 1987 she produced the album Incognito, which became a huge success. Approached by Swiss song writers Atilla Şereftuğ and Nella Martinetti she was chosen to represent Switzerland in the 1988 Eurovision Song Contest singing 'Ne partez pas sans moi'. By winning the contest in Dublin, Ireland on April 30, 1988, she received a large boost to her career in Europe. Her first English-language album, Unison (1990), expanded her international recognition with the breakthrough single, 'Where Does My Heart Beat Now'.
Many of the hit singles that followed over the next ten years ('If You Asked Me To', 'Water from the Moon', and 'Nothing Broken but My Heart') were written by Diane Warren, a composer best known for power ballads. However, Céline Dion finally showcased her talents as a songwriter when she co-wrote 'Don't Save It All for Christmas Day' for the 1998 Christmas album, These Are Special Times and 'Treat Her Like a Lady' on her Let's Talk About Love album, 1997.
In late 1993, she indicated to the public for the first time that she was in love with her manager, René Angélil. In the dedication section of her third English-language album, The Colour of My Love, Dion named Angélil 'the colour of her love'. Eventually, they were engaged, and she married him in 1994. The wedding was broadcast on television across Canada and was very highly rated. The couple also has a son, René-Charles Angélil (born January 2001).

Celine Dion quotes
Because You Loved Me,
-Celine Dion
I wanted to partner with a beauty company that would develop a product in a line with my values. Like creating music, it is important that beauty products appeal to both one's senses and emotions.
-Celine Dion
The way it was said makes it sound like I'm not singing live at my shows, which is not true. In the past, we've used instrumentation and voice samples on the up-tempo numbers. This just gives the dance tracks a bit more punch to enhance the live performance, but I think that's normal.
-Celine Dion
because of air-conditioning, meeting a lot of people, shaking hands -- more chances to get sick.
-Celine Dion
It's All Coming Back to Me Now,
-Celine Dion
I'm approaching 40 years old, and I have to tend to that. This frozen embryo that is in New York is my child waiting to be brought to life.
-Celine Dion
I would love to make a film, ... I want an Oscar!
-Celine Dion
I'm not thinking with my head, I'm talking with my heart.
-Celine Dion
We are comfortable in this environment. Why not make ourselves comfortable over there?
-Celine Dion
I wish we were all naked all the time. I have always believed it's what's underneath that counts. If we were all forced to be naked, perhaps we would start to see it a little bit more.
-Celine Dion
How come it's so easy to send planes in another country to kill everyone in a second, to destroy lives?
-Celine Dion
You know, some people are stealing and they're making a big deal out of it
-Celine Dion
Oh, they're stealing 20 pair of jeans or they're stealing television sets. Who cares? They're not going to go too far with it. Maybe those people are so poor, some of the people who do that they're so poor they've never touched anything in their lives. Let them touch those things for once.
-Celine Dion
We need to serve our country, and be there right now to rescue the rest of the people. We need the cash, we need the blood, we need the support, right now we need the prayers.
-Celine Dion
Celine Dion - Love Can Move Mountains (in the style of Celine Dion)
There ain't a dream that don't
Have a chance
To come true now
It just takes a little faith baby
Anything that we want to do
We can do now
There ain't nothing in our way baby
Nothing our love couldn't raise above
We can get through the night
We can get to the light
Long as we got our love to
Light the way
With a little faith
Just a little trust
If you believe in love
Love can move mountains
Believe in your heart
And feel, feel it in your soul
And love baby love can
Move mountains
Ocean deep and mountains high
They can't stop us
Because love is on our side baby
We can reach the heavens and
Touch the sky
Just believe it, believe in you and I baby
If we got love that is strong enough
We can do anything, make it
through anything
'Coz through it all love will always
Find a way
With a little faith...
You believe in me
I'll believe in you
If we believe in each other
Nothing we can't do
If we got love that's strong enough
Love will find a way
With a little faith
