Look what you made [Amber Rose's son Sebastian] do, Taylor Swift!

Little Sebastian, now 5, got the surprise of his life Tuesday night (March 20) when he received a package from none other than the Reputation singer, who gifted him with concert tickets to Swift's upcoming tour.

"Look at that, Taylor Swift sent that to you," Rose says in the clip above as she hands Sebastian a package.

"Really?!" he says incredulously. "For real?! This is gonna be so exciting! Oh, my god, she sent me a letter!"

"Thanks Taylor!" he says in an additional video.

And fans couldn't get enough of the cuteness.

"This is so cute. i can hear the happiness in your voice girl! Proud mama," one wrote, while another noted "He is such a freakin sweetheart, congratulations Amber. You and and Wiz are awesome parents and have raised a precious jewel."

Sebastian is a loyal disciple of Swift's. Just a few months ago, Rose posted a video of him jamming out to "Look What You Made Me Do."

Swift will embark on a huge Reputation World in just a few weeks, which will kick off at the University of Phoenix Stadium in Arizona on May 8 and will wind around the country until October 6. Additional stops and legs will be announced at a later date, though it's not clear if there will be more United States locations.

Camila Cabello and Charli XCX will join Swift as supportive acts, she announced in a March 1 tweet.

“I’ve been wanting to tell you this for a really long time,” she said “I’m really excited and I hope you are too.”
