Sorry North, but it looks like Penelope Disick may have a new favorite playmate!

Rob Kardashian took to Snapchat on Thursday, Feb. 9, to post a photo of three-month-old daughter Dream bonding with Kourtney Kardashian's four-year-old — and the baby looks like she's almost as big as her toddler cousin!

The duo's aunt, Kim Kardashian, captured a video of the precious moment, using a filter to give the girls cat ears. "Cutest cats in town," the 36-year-old can be heard saying as her grandmother, Mary Jo Campbell, tickles Dream's belly.

This is the first time that Rob and Blac Chyna's daughter has been photographed with any of her cousins. The playdate comes just days after Chyna seemingly shaded her fiancé on social media. "It's funny when people say they wanna be great but sleep until 3 pm etc!" the model wrote on her Snap story.

The duo welcomed Dream on Nov. 10 after less than 10 months of dating, and ran into serious relationship problems almost immediately after. In an Instagram hack of her private messages, Chyna referred to her 29-year-old beau as "lazy, fat, and insecure," which led her to move out of their shared home for a brief period of time.

She also sparked breakup rumors earlier this month after posting a family photo with Dream and older son King Cairo, 4, which noticeably left Rob out.

But no matter where their relationship is at, it's clear that Dream has changed Rob for the better. The proud dad posted a photo of the little munchkin on Friday, Feb. 10, writing, "Today my baby girl is 3 months old and I'm in love with her." In the shot, the cutie — who's her father's twin — is decked out in pink.
