Dad Eddie Cibrian seems to be keeping out of it as the dueling mom and stepmom go wild on Twitter.
It started with The Real Housewives of Beverly Hills star tweeting about the birthday party she hosted Friday afternoon for the older of her two sons with ex-husband Cibrian.
"Mason said this was the BEST cake ever!" she tweeted along with a pic of a cake that appeared to be dripping in blood.
The party seems to have included a show and tell with some wildlife, because Brandi also posted a photo showing her hugging her younger boy, Jake, who was crying while she had a small snake wrapped around her neck and several other boys looked on.
"Jake and mommy were brave also," she commented.
Hours later, it was LeAnn's time to shine in her stepmom role.
"Just had a great time at Mason's 10th birthday party. Such cute kids," LeAnn tweeted Friday night.
She followed it up with, "Night! Trying to get several little boys to go to bed after a big party. LOTS of pizza and sugar!!"
Probably a second cake too.
