Britney Spears has been threatening to tell all about life with her family, and a new Instagram post makes it look like she’s ready to get rolling.

Brit dropped a big hint on Monday, using just a few words. She posted a photo of an old-fashioned typewriter, along with the caption: “Shall I start from the beginning?”

She first railed about the fam back in June, saying “none of them did a damn thing” to protect her during her conservatorship. A few months later, she told Instagram followers, “Lord have mercy on my family’s souls if I ever do an interview!”

Little sis Jamie-Lynn, who’s promoting her own memoir, fired off the first shot on Good Morning America Wednesday morning. She told the audience, “I’ve always been my sister’s biggest supporter, so when she needed help, I set up ways to do so. I went out of my way to make sure that she had the contacts she needed to possibly go ahead and just end this all for our family.”
