Sydney Sweeney is spelling it out.

The actress, 29, wore her “SB” initial necklace in new lingerie photos posted by her brand, Syrn, on Wednesday. The dainty monogram is thought to be a tribute to boyfriend Scooter Braun.

The images promote Syrn’s “Send Nudes” collection, which the label calls “a cheeky and playful take on the classic nude color palette.”

The collection includes 18 pieces, including four new silhouettes, in four skin-toned shades.

Sweeney models the Forever Yours demi bra ($64), giving the lens a smoldering gaze in one shot and posing on a bed for her laptop’s Photo Booth app in another. She also snaps a mirror selfie with a point-and-shoot, the delicate necklace glinting in the camera’s flash.

The “Euphoria” star debuted the pavé charms at Stagecoach Festival in April, where she joined Diplo onstage during his HonkyTonk set. The letters match Braun’s initials, though they could also represent both of their last names or Sweeney’s middle name, Bernice.

The couple met at Jeff Bezos and Lauren Sánchez’s Venice wedding in June 2025, and returned to the city earlier this month, sharing a kiss on a gondola.

Braun, 45, went Instagram-official with the actress in April, captioning a photo from the “Euphoria” Season 3 premiere “lucky bastard.” He got more sentimental in a tribute for her birthday on Sept. 12, calling her “the woman who is the exception to every rule” who showed him “how life with true partnership can be lived.”

Sweeney also bonded with Braun’s three kids over smoothies in Los Angeles earlier this month.

Braun appears to have long-term plans. “He is trying very hard to marry her,” a source told Page Six.
