Mod Sun fans chant ‘f–k Tyga’ after Avril Lavigne split

Karma’s a bitch.

Mod Sun concertgoers chanted “f–k Tyga” during one of his recent shows after ex-fiancée Avril Lavigne allegedly dumped him for the rapper.

Travie McCoy took the stage during Mod’s Wednesday night performance in New York City, praising his good pal for being “one of the most loyal dudes” he knows, per TMZ.

When the Gym Class Heroes musician concluded his speech, he yelled, “F–k Tyga,” which prompted a shocked Mod Sun to run to the back of the stage.

The audience then joined in McCoy’s shady chant, singing it in unison at the top of their lungs as the “Flames” musician smiled.

Mod Sun — whose real name is Derek Ryan Smith — seems to be in better spirits following his split from Lavigne.

Last month, the “Complicated” singer’s rep confirmed to Page Six that she called off their engagement, which came as a surprise to Mod Sun.

His rep told us, “They were together and engaged as of three days ago when he left for tour, so if anything has changed, that’s news to him.”

Lavigne, 38, and Mod Sun, 36, had reportedly been having issues in recent months and been on and off, before finally ending the relationship for good.

He then took to social media to express how heartbroken he was over their engagement being called off.

“In 1 week my entire life completely changed,” the singer wrote on Instagram at the time. “I just know there’s a plan for it all. I’ll keep my head up + always listen to my heart, even when it feels broken 💔.”

The “Karma” musician concluded his message by everyone who has supported him through this tough time as he is on the road.

“Being surrounded by love every night on tour has been an absolute blessing,” he wrote. “I have the best friends in the entire world, thanks for always having my back. See you on stage.”

Despite Mod Sun’s sad reaction, Lavigne did not stay on the market for long as she and Tyga were spotted getting cozy together at Nobu Malibu just two days before news of her split surfaced.

And earlier this month, the Canadian pop-rock star and “Ayo” rapper confirmed their romance by sharing a kiss and holding hands during the Mugler x Hunter Schafer party for Paris Fashion Week.

The new couple then continued their Paris takeover, wearing matching leather ensembles to the Y/Project show.

While Lavigne and Tyga were enjoying their time overseas, Mod Sun took to Twitter, expressing gratitude for his close friends who have been helping him get through this tough breakup.

“I’m so grateful to have real friends who will sit on the phone with me for 2 hours,” he tweeted March 6.

“If you got those people in your life, do not let them go.”

Mod Sun popped the question to Lavigne in March 2022 in Paris after dating for more than a year.

“Yes! I love you forever 💍🥂 Sunday March 27, 2022,” the “Sk8er Boi” singer captioned a post from the proposal at the time, while Mod Sun added in the comments, “love u so much! Forever n ever my angel.”
