Let's start Thursday off with something very adorable: Kaia Gerber and Cara Delevingne have matching tattoos, Gerber revealed on her Instagram Story. Delevingne turned 28 on Wednesday, August 12, and Garber released a photo and video of the two to commemorate the occasion. During Milan Fashion Week earlier this year, Delevigne shared a photo of Gerber's fingers and her toes together, again captioning it "solemate," as Elle reported (opens in new tab).

Gerber also posted a photo of Delevigne wearing a hoodie that read "Kaia" and captioned it "the only person to wear my face on a sweatshirt."

Next, Garber shared a photo of the two of them at the "Black Lives Matter" protest in Los Angeles last month." Best protest buddies," she captioned it.

Finally, Garber posted a video of herself and Delevigne dancing, with the caption, "coolest guys at the function."

In honor of her birthday, Delevigne asked her followers to sign a petition in support of the Break Free From Pollution Act, which aims to reduce the production of single-use plastics. 'On my birthday this year, please join me in demanding that Congress pass the Break Free From Pollution Act and put our planet and public health ahead of corporate profits,' he said. Can you help me collect 28,000 signatures on my 28th birthday?" To sign the petition, click here (opens in a new tab).
