The Hollywood legend recently celebrated 25 years of marriage to Frédéric Prinz von Anhalt, an occasion which von Anhalt had already commemorated with a $68,000 (£41,761) billboard on Sunset Boulevard.
Von Anhalt hosted a gathering at the couple's Los Angeles home on Sunday, welcoming celebrity friends including Quincy Jones, Phyllis Diller, Robert Blake and Frank Stallone, according to The Hollywood Reporter.
He later claimed in a Facebook video that Gabor had been treated like royalty at the party and even wore a tiara and pink gown.
Von Anhalt said: "Look, my wife is 94 years old. She should have everything she wants and should have everything large. This big party is not for the guests, not for the media, nor for me - this big party is for Zsa Zsa.
"It's 25 years of marriage. 25 years of marriage here in Hollywood is a big thing. It's 25 years with Zsa Zsa Gabor, it's a big thing, it's a huge thing, and I made it. So many husbands didn't make it - they only made it a year or two. I made it 25 years so I must have done something right."
Gabor has experienced numerous health problems over the past few years, including a leg amputation in January and several hospital visits, one of which saw her fall into a coma.
