Legendary TV host Bob Barker has died at 99 as confirmed by his longtime publicist, Roger Neal.

He passed from natural causes in his longtime Hollywood Hills home. 

'It is with profound sadness that we announce that the World's Greatest MC who ever lived, Bob Barker, has left us,' Neal said in a statement, obtained by NBC News. 

Barker's girlfriend Nancy Burnet, broke her silence to say that she is 'so proud of the trailblazing work' they 'did together to expose the cruelty to animals in the entertainment industry and including working to improve the plight of abused and exploited animals in the United States and internationally.' 

'We were great friends over these 40 yrs. He will be missed,' his partner, 79, said in her own statement, obtained by People.

The star was the longtime host of the game show The Price Is Right, beginning his run in 1972.

The show, which had been on air since the 50s and was in decline, was revitalized by Barker, who was the face of the show until 2007.

Before that, Bob had taken over as host of Truth or Consequences in 1956. 

The MC, born Robert William Barker, was born in Darrington, Washington, on December 12, 1923.

When he was 6-years-old he moved to Mission, South Dakota, to live on a Sioux Indian reservation with his mom, according to NBC.
