Celine Dion bid a fond farewell to Las Vegas after 16 years of performing there.
But the beloved "My Heart Will Go On" singer, 51, again sparked concern with her scary skinny look!
Dion ended her Sin City residency show on Saturday, June 8, while debuting a new song called "Flying On My Own."
In a heartfelt goodbye speech for 4,298 fans at the Colosseum at Caesars Palace, Dion said, "I'm supposed to know what to say. I am very excited and I am a little bit emotional at the same time. This is our final show in this beautiful Colosseum in Las Vegas. There are lots of wonderful memories, you know, but it's kind of strange at the same time, because when they started to put it together I was here and it was like, 'I don't know.' Then I must have misunderstood something because I thought I was going to be here for three months or something like this, and here we are 16 years later. Maybe we have saved the best for last."
The star also paid tribute to her late husband René Angelil, who encouraged her to perform in Vegas.
"I'm both proud and humbled by what we've accomplished at the Colosseum since we began 16 years ago when René and I first shared this dream. This entire experience has been a huge part of my show business career, one that I will cherish forever," Dion said.
There's no word on what the music icon had to eat after the emotional last show.
Her chest looked bony in a sparkly low-cut gown she wore at the end of the concert.
As RadarOnline.com has previously reported, the famed singer has sported a skeletal frame for some time.
Fashionista Dion has flaunted her toothpick-thin form in bizarre outfits at runway shows and visits to famous designers.

Getting Choked Up
"I have so many people to thank, but the most important 'thank you' goes to my fans, who gave us the opportunity to do what we love," Dion told the crowd.
The Colosseum is known in Las Vegas as "the house that Céline built" for her massive success. Fans were treated to all her hit songs for the last Sin City show.
Like A Bird
Tiny Dion looked like she could float away while performing her new song, "Flying On My Own."
Incredibly, the world famous Canadian-born songbird said before debuting her "Flying" song, "I have to admit that my knees are shaking right now, I'm very nervous."
Love For The Goddess
Dion's fans sang along with her during the concert.
Fans were lucky to be at Dion's sold-out last gig, and cried as she sang such hits as "The Power of Love."
As the show ended, Dion was joined by her band members and her children René-Charles, 18, and twins Nelson and Eddy, 8, who appeared onstage with flowers.
Dion blew kisses to the audience members who gave her a massive standing ovation.
Fans received a letter from Dion that thanked them for supporting her for years in Las Vegas.
Dion first launched her Sin City residency at Caesars Palace in March 2003 and it was called A New Day. In 2011, it changed to simply Celine. Since then, she's played to constantly sold-out audiences with celebrity fan guests. At the end of May, Kanye West took wife Kim Kardashian to see Dion's show for a date night following their 5th wedding anniversary.
Dion appeared fragile in her concert costumes, which included a shiny sleeveless gown. Before, she's shocked onlookers by looking space age in a dramatic braless black jumpsuit with a plunging V-neckline that flaunted her skimpy cleavage in Paris.
Dion was devastated when her husband and manager Angelil died in January 2016. Recently she's appeared thinner than ever.
On Her Own
Dion enjoys being fashion forward onstage and off.
Dion has performed 1,144 shows in Vegas for more than four million fans. Her show has generated more than $700 million in ticket sales. But she continues to cause jaw-dropping shock with her scary skinny look!
