The couple was married on November 20 that same year, and will celebrate their 71st wedding anniversary this year.
Unlike his siblings, who both had morning baptisms, Louis’ christening will be happening in the afternoon, at 4pm.
It will be held in the Chapel Royal at St James’s Palace, which also holds a special place in royal family history.
Chapel Royal was where Queen Victoria married Prince Albert in 1840, King George V married Queen Mary in 1893, and more recently, where Prince George was baptised in 2013.
It’s still not known who will be named as godparents for the little guy.
To be honest though, we’re kind of just looking forward to seeing Louis again.
The young prince hasn’t actually been seen out in public since his birth on April 23, and that’s just two months too long.
