The "Bring The Funny" judge took to social media on Wednesday and asked friends and family who are currently members of the popular workout boutiques to rethink their membership.
"A lot of my cool, socially aware, progressive, awesome, amazing friends are members of Equinox or SoulCycle" she began. "I just want to let you know that their owner is hosting a giant Trump fundraiser."
"F-ck them," Teigen said. "Cancel your memberships today."
Giving her followers an incentive, she offers up her house as a replacement for a workout den.
"Just think about it," Teigen adds. "If you're fine with that [the fundraiser], cool. Go right ahead. But if you're not, and I know a lot of you are not fine with that, cancel."
Teigen, who has been open about her distaste for President Donald Trump, isn't the only high profile person calling for members to boycott the popular exercise franchises.
Sophia Bush, Billy Eichner, Jamie Chung and more celebrities are taking action and are canceling their memberships.
The former "One Tree Hill" star wrote, "Whelp. Buh-bye @soulcycle. Won't miss ya!"
Eichner wasn't far behind.
The "American Horror Story" star tweeted that he canceled his Equinox membership today.
"Money talks, especially with these monsters," he wrote. "If it's too inconvenient for u to trade one LUXURY GYM for antoher, then you should be ashamed."
Chung said she dropped both franchises.
The "Hangover II" actress wrote, "I used to love what they were about but knowing that the CEO helps fund hate. I'm out."
On Wednesday afternoon, #BoycottEquinox and #BoycottSoulCycle began trending on Twitter after news spread that Ross, who is the founder and chairman of the company that owns both brands, was hosting a fundraiser for Trump.
The Washington Post reports that the shindig will go down at his Hamptons home where guests will pay anywhere from $5,600 to $250,000 to attend.
SoulCycle put out a statement in response to the backlash, stating their company "in no way endorses the political fundraising event and does not support it."
Ensuring no profits are being used to fund politics, they encourage fans to keep coming.
"We'll always stay true to our values and committed to our community," it states. "We know who we are and we know what we believe in, and nothing will ever change that."
