Exciting day for Diplo and Kathryn...probably not as exciting for Katy Perry.
To be fair, Katy and Diplo have been on and off for quite some time and according to the Daily Mail, they didn't even start dating until Diplo and Kathryn broke up when she was already two months pregnant.
The little boy, named Lazer Lee Louis Pentz, weighed a healthy 8 pounds, 10 ounces at birth and is the second son for Diplo and Kathryn. According to Us Weekly, the 36-year-old DJ is spending time with his ex and their new addition and has been staying busy buying baby supplies.
All of this must be a tiny bit awkward for Katy, but from what we've seen, she's keeping her thoughts to herself. She hasn't posted any tweets - not even any cryptic ones - since the news broke.
As for Diplo, he's been tweeting up a storm the past few days about things like Taylor Swift's butt, Kim Kardashian's butt photo (we're noticing a trend here) and other random non baby-related stuff.
