The baby boy, Lazer Lee Louis Pentz, weighed 8 pounds and 10 ounces. The baby's name is in reference to Major Lazer, Diplo's electronic music project.

In 2012, Diplo was asked about his relationship with Lockhart during an interview with Rolling Stone but he didn't get into much detail.

"I don't really want to talk about that because it's too personal. But sometimes, I hang out with other girls, I guess. Like at the club in Vegas, there'll be, like, local girls there," he said.

The 36-year-old, who has produced music for Bruno Mars, Britney Spears and Justin Bieber, is now rumored to be dating singer Katy Perry. The two have been linked since Coachella in April.

Diplo was also spotted with Perry in Paris as she celebrated her 30th birthday in October. Photos posted by E! News caught the two together as they arrived in the French city.

"They goofed around on the tarmac and Katy looked cute in her matching Adidas track suit and flip flops," a source told the publication at the time.

"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," the source added. "They were inside for about two and a half hours. Katy looked happy but tired as she was yawning."
