Liz Taylor's secret REVEALED!

The reclusive screen legend, 77,  in mourning since the death of Michael Jackson has been holed up in her bedroom in her Bel-Air, California mansion, watching videos of the reality show RuPaul's Drag Race.

The Cleopatra star has told her friends that it's the "funniest show on TV" and has even sent RuPaul a fan letter with a signed photo.

"RuPaul is her new obsession," a Hollywood insider told The ENQUIRER. "Liz can be moaning in pain from her various ailments, but then she has a staffer pop in one of the RuPaul shows and suddenly she starts to laugh.

"She can't get enough of the drag queens!"

Liz's celebrity hairdresser, Jose Eber, turned her on to the Logo network's drag competition, where contestants dressed as women compete for the ultimate title of America's Next Drag Superstar.

"Liz claps when the drag queens she's picked win," said the insider. "These days there's not a whole lot that makes her happy. Liz is wracked with pain and her mobility has been seriously limited.

"So to see her light up watching a bunch of guys dressed as women is a kick."
