Kaley Cuoco and 3-Month-Old Daughter Matilda Are Totally Twinning in Precious Selfie

The actress appropriately added a 'mini-me' sticker to the sweet snap.

Growing so fast! Kaley Cuoco's daughter, Matilda, looks just like her mama in an adorable new selfie. 

The duo make the same surprised expression as they gaze off-camera, with the three-month-old baby sitting up -- wide-eyed and alert -- in Cuoco's lap. Matilda is showing off luscious, full cheeks and a bit of peach fuzz on top of her head while both mama and baby are rocking summer-friendly tank tops. The Big Bang Theory alum threw a fitting "mini-me" sticker over the image. 

Cuoco welcomed her first child in March with partner Tom Pelphrey. Since then, she's been generous with sharing plenty of photos and videos of her new little bundle. 

"I've become that mom who posts every freaking thing," Cuoco cracked in an interview with ET in May. "She does something, and I'm like, 'I have to post that!'"

Last week, Cuoco and Pelphrey enjoyed a date night out in Los Angeles to take in a performance of the musical Beetlejuice

The actress also shared a sweet snapshot of Matilda -- nicknamed "Tildy" -- bonding with her favorite dog while announcing a new side project of her own. 

"🐾 Tildy and our dogs were instant besties, especially her and Opal, who is pretty much Tildy's shadow these days!" she wrote. "Head on over to @ohnorman for my tips on introducing a new human to your dogs! ❤️

Last month, Cuoco opened up to ET about the recent loss of one of her beloved rescue pets, Dumpy. 

"You know what, this is the hard thing about rescuing dogs. Like, this is what you risk," Cuoco shared. "We're like, 'Why do we keep doing this when we know they're gonna break our hearts?'"

"And that's why we do it. And we do it over and over and over again," she shared. "He was such a blessing in our lives and everyone that met him... there's a lot of memories there."

Meanwhile, Cuoco also recently opened up about the idea of giving Matilda and their fur babies another human sibling.

While appearing on the Smartless podcast, hosted by Jason Bateman, Sean Hayes and Will Arnett, the 37-year-old actress was asked if she wants to have more children.

 "Yeah, we do," she told the hosts.

The Flight Attendant star added that she became pregnant two months into her and Pelphrey's romance. "We're like, boom, boom, boom. We're in sync," she said. 

Cuoco, who noted that they are "lucky," shared that she and the Ozark star's relationship has survived post-baby because they have help and support.

"My mom is the best and actually, so is Tom's mom," she said. "They come in and help, they don't overstep. It's the best."
