Love is in full Bloom!
Since the Lord of the Rings star last blew out the candles, his show Carnival Row premiered, he inked a first-look deal with Amazon to develop TV and film projects and, oh yeah, he got engaged to Katy Perry!
We've been obsessed with the duo's love story ever since we first spotted them getting flirty together at a Golden Globes after party four years ago.
Since then, the two have had their highs and lows, including when they split temporarily in 2017, but we couldn't be more thrilled that they are on their way to their happily ever after together.
In honor of the Pirates of the Caribbean performer's birthday, we're taking a look back at his cutest pictures with Perry, from their red carpet appearances to their moments with their precious pups.
