The pair, who announced their nuptials in April, have split citing irreconcilable differences as reported by Today.
Appleton filed the divorce paperwork in a Los Angeles court on 12 November but listed 10 November as the date of separation from Gage.
Appleton and Gage signed a post-nuptial agreement on 3 May that waived the need for spousal support and both will leave the marriage with the same individual assets, as the documents say.
The estranged couple married on 22 April, in Las Vegas, with Kim Kardashian officiating and country star Shania Twain present.
“We did it,” Appleton posted on Instagram announcing their engagement.
Euphoria actor Gage posted the same series of photos at the time saying, “ring finger where the rock is,” nodding to the rock and roll ASL sign he displayed in the first picture.
Gage and Appleton first publicly confirmed their romance in March while making their red carpet debut at the Vanity Fair and TikTok Young Hollywood party.
