Kaia Gerber and Cara Delevingne continue to push their relationship forward, with Gerber posting a set of matching foot tattoos the pair apparently got this week in honor of Delevingne’s 28th birthday.

“Happy birthday to my solemate,” the 18-year-old Gerber posted on Instagram alongside pictures of the duo’s hands interlocked and another of the matching ink, which read “solemate” and are, yes, placed on the inner arches of their feet.

Gerber also uploaded a shot of Delevingne warring a white hoodie with Gerber’s face and name on the front and another of the pair of them at the Black Lives Matter protest they attended in July.

Absent in this particular expression of affection is Margaret Qualley, whom Delevingne posted a similarly lovey Instagram tribute to earlier this week.

Gerber weighed in on Delevingne’s post featuring Andie MacDowell’s 25-year-old daughter, writing, “I feel lucky to know you both.”.
