Happy birthday to Jonathan and Drew Scott

The Property Brothers turned 40 on Saturday, and they couldn't help but celebrate with a few hilarious throwback pics.

Jonathan took to Instagram to wish his twin brother a happy birthday with a sweet photo of the pair clowning around as kids, proving they've always had a silly side. 

In the pic, Drew strikes a pose in his bald cap while Jonathan adorably smiles for the camera, showing off his oversized bowtie. 

"This pretty much sums up the last 40 years with my best friend. Thanks for always having my back @mrdrewscott :) #happybirthday ?," he wrote.

Drew, meanwhile, shared a snap of Jonathan singing into a paint roller. "Retweet to wish the best brother in the world a big #HappyBirthday ???," he tweeted. "@MrSilverScott thanks for making me laugh every day these past 40 years❤️???? #twinning." The pair's network also shared a few throwback pics in a happy birthday post. 

Their 40th birthday isn't the only big event the brothers are celebrating this year. In November, Drew told ET all about his upcoming spring wedding with Linda Phan. 

"To be honest, our lives are always busy. But nothing is ever going to let me slow down on tying the knot with the woman that I love," he gushed. "We don't want to slow down."

"We've narrowed down the location. We're doing a wedding in Europe, but we haven't exactly picked a final city yet," he continued. "Once we do, then everyone will hear about it!"
