"I just don't think it suits me right now," she insisted. "But I'm very happy with the title that has been bestowed upon me."
The "Vanderpump Rules" boss revealed earlier that day at her Annual World Dog Day celebration in West Hollywood that her daughter Pandora is expecting her first child with husband Jason Sabo.... and that more importantly, she shall henceforth be known as "Nanny Pinky."
While that is famously her favorite color, some speculated it may also be a hint at the baby's gender. Lisa confirmed that she did indeed know — and has known for some time — whether the incoming blessing is a granddaughter or grandson.
But she certainly wasn't spilling — nor would she be drawn on which she was hoping for.
"You know what, whatever, I'm just happy," she said. "You know what? We've known for a long time so we kept it a secret."
She confirmed the family did host a little private gender reveal at home, but insisted: "It's not my story to tell — It's Pandora's".
When asked if she was going to spoil the baby however, she did reply in the negative... although it's very possible there was more than a hint of sarcasm in there.
The RHOBH alum was also asked if she had any names picked out, but she didn't fall for that one either, once again keeping (grand)mum.
Of course, Lisa couldn't finish the day without a lighthearted sting at her former friend-turned-nemesis Kyle Richards.
When asked if she'd reached out to her ex-castmate after her scary bee encounter the week previous, she replied with a smirk: "No I just... I mean if I said something, I guess I'd tell her to buzz off."
