TMZ Live

Dee Snider just unleashed a bitter rant about Twisted Sister drummer A.J. Pero's death -- saying his heart attack was totally avoidable, but Pero did nothing to save himself or protect his family.

Dee came on TMZ Live to talk about the band's upcoming farewell tour, but ended up venting about Pero. Dee told us he's in the anger stage of grieving because ... he says Pero knew he had a history of heart disease in his family, but never got checked out.

A.J.'s autopsy results -- which Dee revealed -- are what really set him off about his friend's death.

Manuela Arbelaez thought her "Price Is Right" modeling days were over when she accidentally gave away a car, but it turns out ... she should actually be in line for a raise.

Arbelaez was a guest on "TMZ Live" Friday and told us ... she was probably the only person NOT laughing after her epic gaffe. She figured she was a goner until producers told her they thought the whole thing was hysterical.

In fact, Arbelaez now figures the show got more in free press from the blunder than the cost of that Hyundai Sonata SE. That might be a stretch, but more importantly -- how freakin' hot was Manuela on TMZ Live?

Enjoy.

"Teen Mom 3" star Mackenzie McKee blames her no-good husband and diabetes for the crash that almost totaled her SUV ... but mostly her husband.

The MTV star told us on TMZ Live ... she was looking for Josh when she drove her Kia Sorento into a ditch.

She told us what Josh was doing in the Oklahoma boonies ... turns out he's just wild about hogs.
