The catwalk just got a little catty.

Joan Smalls fueled feud rumors with Candice Swanepoel by posting a cutting two-word response amid reports that the latter is dating Tom Brady.

Last week, Just Jared shared an Instagram post where eagle-eyed fans questioned if the supermodels were no longer friends after they allegedly unfollowed each other on Instagram.

Smalls, 38, took to the comments section, seemingly confirming the news, writing, “Two words: ‘SUMMER HOUSE!’ That’ll explain everything.”

While it’s unclear what part of the hit Bravo show Smalls is referring to, the reality show’s most recent season showed Amanda Batula and Ciara Miller’s friendship implode after the former began secretly dating the latter’s ex, West Wilson.

In other screenshots obtained by DeuxMoi, Smalls labeled Swanepoel, also 38, a “backstabber” when a fan asked if they were not friends.

Joan allegedly responded, “im not friends with backstabbers.”

In a separate now-deleted message, Smalls said there “was no girl code” with some people.

“And the disrespect and carelessness in how they treat you is so unimaginable. There’s no going back. Some people lack humility and moral compass,” she added.

“And the way they gaslight, lie and minimize your feelings is the worst slap in the face after 15yrs or friendship. Not a sorry said or written. Onwards and upwards!!!”

Page Six has reached out to reps for both Smalls and Swanepoel for comment but did not immediately hear back.

While it’s unclear what caused friction in their friendship, the comments came as reports surfaced that Swanepoel is dating Brady.

DeuxMoi previously reported Smalls and the former NFL star, 49, allegedly dated on and off for approximately a year.

However, over the weekend, Us Weekly reported that Swanepoel and Brady have been dating for “a while.”

Additionally, an insider told People that the pair “both live in Miami, so it’s very convenient.”

Sources told Page Six Brady (seen above at the WRE x Palm Tree Residences Miami sales gallery dinner on Oct. 15) “really likes” Swanepoel, but their romance isn’t too “serious.” Seth Browarnik/INSTARimagesThe seven-time Super Bowl champ was previously married to supermodel Gisele Bündchen (seen above in a selfie with Brady). gisele/Instagram

“They’re spending a lot of time together. Candice and Tom have been dating for months,” the source continued. “She’s been very secretive and selective about who she’s told about their dating.”

The source also said the duo has “gone [to great] lengths not to be spotted” together.

Page Six exclusively reported that the seven-time NFL champ “really likes” Swanepoel, but their months-long romance isn’t too “serious.”

Brady was previously married to supermodel Gisele Bündchen from 2009 to 2022.
