Avril Lavigne is showing some love for one of her biggest fans: San Francisco 49ers player George Kittle. 

On Wednesday, the Canadian singer-songwriter shared a video on Twitter — originally posted by NFL Canada — of a virtual appearance she made during a 49ers game to surprise the football player who was clearly overcome with joy. 

"Oh hey there George, it's your friend Avril Lavigne from Canada, eh," Lavigne said to Kittle.

"I'm just going to grab a pop and sit down on the chesterfield now. You guys have a good game, eh." 

He was a sk8r boi she said oh hey there George!

Lavigne's surprise came after a video was shared to social media of Kittle pumping himself up for a training session while singing her ever-popular and much loved hit, Sk8er Boi. 

Kittle just so happened to be "mic'd up" during this impromptu performance.

"Need to put on a performance she can be proud of...Let's get things going this Sunday!!" someone else wrote.

Others took the opportunity to poke some light-hearted fun at Kittle's singing voice. 

George is a gifted football player and has a fantastic personality, which is lucky because he’s sure not going to make a living as a singer!

If Kittle's heartwarming reaction to getting a shout out from the one and only Avril Lavigne doesn't make you smile, we don't know what will.
