Rob Lowe is speaking out against his family’s ex-babysitter, saying that she is demanding money from him or else she will spread lies about he and his wife.

Lowe posted a blog on Monday’s Huffington Post saying that the woman is asking for $1.5M in exchange for her silence.

He writes, “It is an attempt to damage and humiliate not only my wife and me, but our two young sons as well. My family is devastated at this betrayal; this woman worked in our home and traveled with us off and on for seven years, without complaint.”

Lowe also posted what he claims are two text messages from the woman who apologizes kindly for abruptly quitting.

One of the messages reads, “Thank you so much Sheryl and I really am sorry. Please tell the kids it had nothing 2 do w them, they are absolutely amazing boys. It had nothing to do with you or rob either, this was me. I love you guys. Ps tell rob I’m really sorry as well.”

— UPDATES —

TMZ is reporting that the Santa Barbara County Sheriff extended a hand to Lowe, saying they would be more than happy to launch a criminal investigation as extortion is a matter to be taken very seriously and is often considered a felony.

The weird thing? Lowe is refusing any help saying, “Your involvement isn’t necessary. We are going to handle the matter civilly.”

Whoa.  Huge f*cking red flag, right?

The woman is now alleging she had sex with Lowe which he is adamantly denying.  She also accuses him of sexual harrassment.  Lowe claims that she showed up to work high and put his children in jeopardy.

But things are getting even more twisted.  Lowe is also accusing his personal chef of having sex “with third parties” in his bed, snooping for prescription drugs, and stealing the family’s food and mail as well as a ton of other things.  The chef told TMZ he had no clue about the allegations or the lawsuit.
