Montauk, New York - The cast of Summer House invaded a bar in Montauk on Sunday in support of Jesse Solomon, and among a few fresh faces in the mix adding fuel to Season 11 cast rumors was a Taylor Swift-sized surprise.

What would Jesse Solomon do? Well, he'd invite his Summer House castmates to his end-of-summer show near Montauk featuring one of Taylor Swift's backup singers – sans Bravo cameras – putting possible new housemates in the upcoming season on display.

TAG24 News was in attendance and witnessed OG cast members Lindsay Hubbard, Carl Radke, and Kyle Cook all in attendance at The Stephen Talkhouse in Amagansett on Sunday night, as well as Season 10 newcomers Bailey Taylor and KJ Dillard, and rumored Season 11 newbie and influencer Jane Motion. Remi Bader was also in attendance! An unidentifiable man was hanging with the Summer House crew, too, meaning he could be a new cast member, as well.

In snaps of the night shared by cast members, Jesse and Jane appear to be quite cozy, furthering online speculation that the two will be romantically linked in the reality show's eleventh season. Notably missing from Jesse's show was Ciara Miller, who is likely a bit preoccupied with prep (and a cross-country move) for Season 35 of Dancing With the Stars.

Swifties will likely recognize someone from Taylor Swift's world in videos from Jesse's show, as the reality TV star-turned-singer's backup singer on stage with him on Sunday was none other than Melanie Nyema, who has appeared on numerous tours alongside the I Knew It, I Knew You singer – including on The Eras Tour.

As for whether Sunday night's show will appear on the next season of Summer House, while camera crews were not on location, Kyle and other cast members were spotted videoing themselves on their phones throughout the night, and that footage is likely to make the final edit!

Summer House is currently filming Season 11, which longtime cast member Amanda Batula will not be a part of following backlash to the news of her romance with Ciara's ex, West Wilson.
