I think you're right on the money with the numerology, she died on January 12th and her son died on July 12th two years and six months exactly apart. July and January 12th are 6 months apart:
Is this Lisa Presley spotted alive at Jeff Becks funeral? ( the blonde in the back with shades on ) LMP and Mike Lockwood were Jeff's friends.
I'm a noob and idk how to send attachments here so click da link
There are many pics of other celebrity guests at this funeral, however the only guest that comes close to the dress sense is Rod Stewarts wife however her head shape is different, her hair is messier in the wind, the scarf/ collar is different, Alleged LMP is wearing lipstick whilst Rods wife isn't. There is also a button difference in their coats as one is a yellowish tag whilst the other is a black button.
Big difference is Alleged LMP photo appears to be wearing a dress or veil over the lower legs where as Rods wife clearly just wears a coat.
