The always-stylish 33-year-old, who's still rocking her new bangs, showed up wearing a bright blue Reiss coat, while Prince William, also 33, looked dapper in a navy blue suit and printed tie. It was Middleton's second major royal outing since giving birth to Princess Charlotte in May, after visiting students at the Anna Freud Centre in London on Thursday.

As usual, the lovebirds were the center of attention at the stadium, laughing and smiling throughout the match between England and Fiji.

Just how sweet was the royal duo? Here's a play-by-play of their adorable rugby date night:

First, they lovingly gazed into each other's eyes.

Who knew a couple could make applauding look so good? Because they did when they clapped for Honorary President Prince Harry during his opening ceremony speech.

Sharing secrets is no fun, but we guess we'll let this one slide.

By the looks of Middleton's expression, something must have been funny.

It's official: When it comes to cute celebrity couples, the royal couple hands down wins this match!

Kate Middleton and Prince William have pretty much always been this delightful. The duo, who are parents to 2-year-old Prince George and two-month-old Princess Charlotte, started dating over 12 years ago and both were attending university at St. Andrews. They've been married for over four years and that spark is clearly still there after all this time! Watch the video below to see Prince William gush over his family.
