This week should've been one of joy for Kris Aquino. Not to say she isn't happy about celebrating her son's birthday, or about her new movie — it's just that she could've done without the obvious stress that came with fuming at her ex-husband.

She continued her rant from a day before about James Yap's birthday greeting for their son Bimby — which offended her as she said that it made her look like a bad mother.

"Did you really think I would back down?" Aquino began her note posted on Instagram Saturday, adding that she wanted to throw up after seeing Yap write things such as he misses his son "every day," he would "always" be there for him, and he'll forever be Bimby's "papa."

Aquino clapped back by pointing out that Yap did not say a single word when their son was publicly bashed for being "baklain" and "lampa."

"Bullying of an innocent child ang naganap at ikaw walang pakialam na nanahimik --hindi ako magagalit bilang nanay sa pagka-fake ng salita mo?" she asked.

She also said that she's fine with being the target of all the mudslinging, but know that she will be up in arms if someone drags her kids into the conversation. "Kailan ba ako naglalabas ng galit? Kapag mga anak ko na ang ginagamit at pinagmumukhang may mali sa akin bilang ina," she said.

"Dahil sabihin niyo na ang lahat BUT MY SONS ARE LIVING PROOF that they are being raised with the love of a warrior queen."

Yap has yet to respond to Aquino's criticisms of him on social media. His latest post showed him taking his motorcycle out for a spin with friends.
