The resemblance between Alyson Hannigan and her daughter Keeva is legend—wait for it—dary.

Fans had to do a double take when the How I Met Your Mother actress snapped a selfie with the 14-year-old during a recent visit to a Jellycat pop-up in Los Angeles.

As seen in a Sept. 26 Instagram post, Hannigan and her mini me looked almost identical with their matching red hair, which they styled with similar middle parts.

"That’s your exact twin," one commenter wrote, while another quipped, "I only see two Alysons."

A third fan even joked that Hannigan's husband Alexis Denisof's genes "didn’t stand a chance," with many others joking that it was basically a "copy & paste" job.

It's a sentiment familiar to Hannigan, who shares Keeva and 17-year-old daughter Satyana with her former Buffy the Vampire Slayer costar. In fact, the 52-year-old said her teen girls now can now see just how much they actually look alike by revisiting their parents' show.

"I think what's amusing to my daughters is that because people always come up to them and they're like, ‘Oh, you look just like your mom,’" Hannigan told People last year. "Now they actually have the proof. They can see footage of me at their age."

But Hannigan's girls also takes after her crafty personality, embracing all-things DIY. As she noted in her Sept. 26 Instagram post, Satyana is "the true artist in our family" after creating a custom Jellycat-themed manicure for the outing.

"Had the BEST time," Hannigan wrote in the caption. "We had so much fun and I could not be more grateful for this custom Jellycat manicure by my daughter @satyana_art."
