The model announced she'd given birth earlier this week by sharing a touching snap of her breastfeeding the new-born - she also revealed the name: Sylvester Apollo Bear.
Yep, she's managed to give her baby both a first and middle name with links to the popular movies, with Sylvester obviously being the name of Rocky star and creator Sylvester Stallone and Apollo being the first name of Rocky's rival-turned-pal Apollo Creed.
As you can imagine, fans of the movie franchise have been quick to point out the connection, with one person posting on Twitter: "Emily Ratajkowski must be No.1 fan of all Rocky films with that baby name."
Someone else joked: "Emily Ratajkowski literally watched Rocky III and was like I've found the perfect name for my child."
A third person asked: "Is Emily Ratajkowski the number one Rocky stan?
Of course, it's very likely that Ratajkowski and Sebastian Bear-McClard didn't even spot the connection to the movies, but we'll know for sure if they have any more children and choose Adrian, Paulie or Ivan.
The first-time parents announced their pregnancy back in October, with Ratajkowski breaking the news via Vogue magazine where she featured on a new digital cover cradling her bump.
Posting the cover on her Instagram, she wrote: "Grateful and growing. Thank you @voguemagazine for this very special cover."
Before his arrival, the couple decided they didn't want to 'force gender stereotypes' on the baby, so decided not to disclose his gender.
Writing in the magazine, Ratajkowski said: "Who will this person be? What kind of person will we become parents to? How will they change our lives and who we are? This is a wondrous and terrifying concept, one that renders us both helpless and humbled.
"I like the idea of forcing as few gender stereotypes on my child as possible. But no matter how progressive I may hope to be, I understand the desire to know the gender of our foetus; it feels like the first real opportunity to glimpse who they might be.
"As my body changes in bizarre and unfamiliar ways, it's comforting to obtain any information that might make what's coming feel more real."
