Cara Delevingne and Kaia Gerber are celebrating being solemates by getting matching tattoos. The gorgeous English model turned 28 on Wednesday, and her friends and fellow supermodel Kaia Gerber took to her Instagram account to wish her a happy day and giving her followers a glimpse of matching tattoos they have on their feet.

"Happy birthday to my solemate @caradelevingne," the 18-year-old supermodel wrote in her post and accompanied it with a photo of them hugging feet. Gerber went on to share more tributes to the Suicide Squad actress by sharing several more photos and a sweet message about Cara being the only person who wears her face on a sweatshirt.

Gerber describes her in the message as the "best protest buddy," referencing their participation in the Black Lives Matter protest in Los Angeles, and atop of clip of them dancing, "coolest guys at the function." One of the photos showed the models' feet with tattoos of the word "solemate" along the arch of the foot.

Delevingne and Gerber recently posted a picture on social media showing them wearing an oversized cable sweater, marking the release of Taylor Swift's eighth studio album, Folklore. Gerber shared a mirror selfie with Delevingne and wrote that they loved their Cardigan, which is also the first single from the album.

Aside from Kaia, a slew of other stars wished Delevingne a happy birthday. Margaret Qualley shared a post on her Instagram account to wish Delevingne a happy birthday and to let her know that she considers herself to be incredibly lucky to have her as a friend.

Supermodel Joan Smalls wished her a happy "burfday" on her Instagram Stories, advising the 28-year-old actress to continue turning up and shining through. Fashion model Georgia May Jagger also shared an Instagram post to let the model know that she can't wait to be old dog-obsessed ladies that sit on the porch with towels wrapped around their heads and chat.

In early April, a source told PEOPLE that Cara and her longtime girlfriend Ashley Benson have had their ups and downs in the past, but it is over now. Another source said at the time that Delevingne had been spending a lot of time with friends including Margaret, Gerber, and Rainey Qualley while quarantining during the coronavirus pandemic.

Delevingne and Gerber even attended the Black Lives Matter protest along with dozens of other protestors in downtown Los Angeles. The pair stood outside the Hall of Justice and shared the event on social media.
