Elle Fanning knows there's no better time to poke fun at your sibling than on their birthday!

On Tuesday, The Great actress wished her older sister Dakota Fanning a happy birthday with a funny post Instagram in which she referred to the Uptown Girls star as an "actual alien from the future."

In the silly-yet-sweet tribute, Elle included a hilarious video of Dakota singing along to "WAP" by Cardi B and Megan Thee Stallion while paddleboarding across a pool using a skimmer net.

"Yes, there's a lot more where this video came from 💦," Elle, 22, teased in the caption.

"Happy 2️⃣7️⃣ Birthday to the one who apparently is an actual alien from the future," the actress joked. "A psychic told me you are a more advanced human being than the rest of us and have come to the past to help us all along."

"I love you doesn't come close to how I feel," Elle kindly concluded the post.

Amused by the humorous post, Dakota replied, "I'm DEAD!"

"I looooooooove you," the I Am Sam star added.

Phoebe Fox, who appears on The Great with Elle, was impressed by Dakota's simultaneous paddle and rapping talents, writing, "These are some serious SKILLS"

Earlier this summer, the celebrity sisters showed off another unique skill when taking part in TikTok's popular #WineChallenge.

Dakota shared a video on her Instagram which showed Elle holding the base of a half-filled wine glass between her teeth while slowly leaning backward onto Dakota so that the older sister could drink the wine from behind her.

The actresses were successful in completing the challenge, both cheering after Dakota gulped down the mouthful of wine.

They both received some praise from their famous friends at the time. Ashley Benson called the video "genius," while Selma Blair added, "This is wonderful. Much Love."

Dakota has previously opened up about her tight bond with Elle, including in the 2019 July/August issue of Shape.

"My sister, Elle, and I are really close," Dakota gushed at the time. "We always have been. We're very different, but we're very connected. We don't talk every day, but we don't have to. We just have that special bond."

"There's no one I want to succeed more in this business than my sister, and I know she wants the same for me," she added.
