Kailyn Lowry from "Teen Mom 2" is actually a teen mom of three now... and all three are boys!
Radar confirms the baby weighed in at 7 lbs. 15 oz., and does not yet have a name.
The father of Lowry's latest son is her ex, Chris Lopez, she confirmed on May 2.
Lowry's other sons are Isaac Elliot, 7, with ex-boyfriend Jo Rivera; and Lincoln Marshall, 3, with ex-husband Javi Marroquin.
Earlier this year on her blog, Lowry wrote, "Having another child is something I am so happy about and I just can’t wait. My boys are so excited, those who love me are so excited, and I hope that everyone can just be happy for me during this time."
