Katy Perry’s boyfriend, Diplo, welcomed his second child with his ex Kathryn Lockhart over the weekend.

Lazer Lee Louis Pentz was born 8 pounds, 10 ounces and is the second son of the Los Angeles-based DJ/music producer and his ex. The Diplo and Lockhart are already parents to son Lockett, who is 4. According to Us Weekly, which exclusively broke the story, Diplo is currently spending time with Lockhart and his new son.

You might remember Katy Perry’s boyfriend from his recent, highly-publicized feud with Taylor Swift. On November 12, the 36-year-old tweeted that “Someone should make a kickstarter to get taylor swift a booty” (tweet below):

While many tweeters condemned Diplo’s tweet (with one writing “@diplo someone should make you a kickstarter bc no one knows who the f–k you are,”), the most high-profile response came from singer Lorde:

“@diplo should we do something about your tiny penis while we’re at it hm.”

Ouch! Diplo later responded, calling Lorde a “high school student,” continuing, “Disappointed that swift boat veterans didn’t get my tiny dick a fundly going (enlarge my bae).”

Apparently, the real feud is reportedly between Swift and Perry. The former has implied in the past that her song “Bad Blood” is about Perry, though she did not name the singer directly. After Swift hinted at the connection in an interview, Perry tweeted: “Watch out for the Regina George in sheep’s clothing…”

At least Katy Perry’s boyfriend is around to defend her honor, right? Here’s “Bad Blood” (just the lyrics, because music rights). You decide what it’s about:
