Is Katy Perry getting revenge at the birth of DJ Diplo's baby as she reportedly flirted with One Direction hunk Niall Horan at the ARIA Awards? During the same event, the "Roar" singer reinvented the brooches.

"Katy isn't one to hold back when she wants something and she proved this yet again, when she sought out Niall on the red carpet at the ARIA Awards," the Hollywood Life said.

One Direction hunk Niall Horan and "Dark Horse" singer Katy Perry were in Sydney, Australia and found themselves crossing paths on the red carpet. "It was then that Katy allegedly locked on to the 1D hottie and snagged him for a warm embrace, leaving him confidently smiling from ear to ear," the article said.

Now rumors have been flying that Katy Perry is trying to get back at DJ Diplo, her rumored boyfriend, whose ex just gave birth to their second child. According to Us Weekly, they named him Lazer Lee Louis Pentz and the baby weighed 8 pounds to 10 ounces upon birth.

Meanwhile, Katy Perry was spotted wearing a strapless dress with Victorian-inspired brooches during the same event.

"Replicas of the antique and vintage style brooches, historically produced in the 18th and 19th centuries and carved largely from shell and semi precious stone, added a regal look to her ensemble," MailOnline.

A previous report from E! News seemingly confirmed the report of "Roar" singer Katy Perry dating DJ Diplo, who's real name is Wesley Pentz, as the two were spotted stepping out of the Le Bourget airport in Paris.

"They goofed around on the tarmac and Katy looked cute in her matching Adidas track suit and flip flops," the witness told the website.

"Katy was seen dressed up with her entourage as they walked to the very romantic Restaurant le Jules Verne on the second floor of the Eiffel Tower. They were inside for about two and a half hours. Katy looked happy but tired as she was yawning," it said.
