Beyoncé and Jay-Z's babies are growing up!
On Wednesday, the singer shared a year-in-review video on Instagram, which included two never-before-seen photos of the twins, and it should come as no surprise that they're absolutely adorable!
The final photo in the video shows the twins posing with their family. Little Sir is sitting on his dad's lap and wearing a matching tuxedo, while Beyonce, Blue Ivy and Rumi look glamorous in white dresses.
Rumi and Sir also make an appearance around the 52-second mark in the video, where the smiling twins pose for a photo on their second birthday back in June. In another blink-and-you'll-miss-it moment, Sir adorably toddles around at the party.
Rumi bears a striking resemblance to her older sister, who happens to look a lot like their mom as a child. Many people took to social media to also point out how much Sir looks like his daddy, especially with that hairdo.
While Beyonce has a lot to celebrate after another stellar year, the singer has one very important party coming up: Blue Ivy's birthday! Beyonce's oldest daughter will be blowing out eight candles on Jan. 7.
Happy birthday, Blue!
