Many were startled when Avril Lavigne was photographed with Tyga a few weeks ago, especially considering everyone knew she was engaged to Mod Sun.

Avril and Mod Sun's year-long engagement and two-year romance ended last month, with the latter claiminghis "heart feels broken."

An insider told TMZ that his divorce from the Canadian rock star had taken the "Rich Kids Destroy Everything" rapper by surprise.

The rapper, actual name Derek Smith, is having trouble seeing pictures of the "I'm With You" singer kissing her new love interest.

"Mod's been down in the dumps since his separation from Avril, which was far from mutual," one source added.

They said, "As if being blindsided by the abrupt end to their engagement wasn't bad enough, he feels devastated by her budding romance with Tyga."

Avril and Tyga were spotted out and about in Paris for PFW and were packing on the PDA.

Numerous individuals witnessed the two locking lips during a Monday night function. Mod Sun was allegedly greatly triggered by such images.

Mod Sun has also alleged that the "Sk8er Boi" singer's behavior is a smack in the face since he feels it is spiteful against him despite the fact that he has done nothing wrong.

Reports claimed Avril Lavigne chose to end things with Mod Sun during his "God Save The Teen" tour.

According to sources close to Avril, she said they were on-again, off-again for months until things stopped working.

But, sources close to Mod Sun denied the allegations, claiming that they were "totally together" and even shared a residence.

Danielle, his sister, also uploaded a message in support of her brother, marking it "Family first."
