In Touch Weekly has an interesting theory on what caused the war of words between Octomoms Kate Gosselin and Nadya Suleman.

Tabloid tattles claim Suleman, now a mother of 14, is furious that the star of TLC’s Jon & Kate Plus 8 snubbed an opportunity to appear on her upcoming documentary series.

“Nadya originally reached out to Kate and asked her to make a guest appearance on the documentary,” an In Touch insider reveals. “Kate didn’t turn down the offer, she just never responded, and that probably made Nadya upset.”

During her two-hour FOX documentary Octomom: The Incredible Unseen Footage on Aug. 19, Nadya criticized Kate’s post-baby bikini body and blasted the reality star as a fame-seeker.

“If Kate won’t appear on-camera, Nadya will just talk about her,” the snitch explains. “Nadya is cunning and has more tricks up her sleeve She’s going to go after both Kate and her estranged husband, Jon.”
