Turner was spotted walking arm-in-arm with Swift, Jonas' ex-girlfriend, in New York City on Tuesday night on their way to dine at Italian restaurant Via Carota, a hot spot for Swift sightings.
The "Game of Thrones" alum went glam with a glittery silver halter top and gray trousers and the "Lavender Haze" singer opted for a red sweater dress underneath a long jean jacket in photos obtained by Just Jared and People.
Turner and Swift's girls' night comes two weeks after the Jonas Brothers singer, 34, filed for divorce from the "Game of Thrones" actress, 27, in Miami-Dade County court, according to court documents reviewed by USA TODAY.
The petition for dissolution of marriage filed by Jonas says "the marriage between the parties is irretrievably broken."
"After four wonderful years of marriage we have mutually decided to amicably end our marriage," they wrote. "There are many speculative narratives as to why but, truly this is a united decision and we sincerely hope everyone can respect our wishes for privacy for us and our children."
Swift's sisterhood with Turner is poignant considering the singer previously dated Jonas for a few months in 2008. That relationship is rumored to have inspired some of the songs on Swift's album "Fearless" and the Jonas Brothers song "Much Better."
Their outing, however, isn't too big of a surprise, as the "Survive" actress has been vocal about being a Swift fan.
She added, "Although, 'Reputation' was inspired by, or partly inspired by, Sansa and Arya Stark."
Jonas agreed with her take, telling Turner, "'1989' is a great album. Bangers!"

Luckily for Turner, "1989 (Taylor's Version)" will be available Oct. 27, the same date the original album was released nine years ago.
"Surprise!!" Swift wrote on X, the social media site formerly known as Twitter, when announcing the album last month. "The 1989 album changed my life in countless ways, and it fills me with such excitement to announce that my version of it will be out October 27th." She added that "1989" was her "most FAVORITE rerecord I've ever done."
