LiLo -- AliLo's Show Could Be "Toxic"

Lindsay Lohan is getting worried for little sis Ali – she thinks the new pimp-out reality show momma Dina's doing with Ali could be big trouble. And LiLo knows toxic.

The Chicago Sun-Times reports that, according to "a longtime Lindsay associate and friend," Lindz is worried that the show has the potential to be "really toxic" – sound like code for Britney? – and that Ali's life could end up as effed up as hers.

As TMZ told you last week, Lindsay's been battling her own demons because her wackadoodle parents won't stop squabbling.

This should be fun, or at least funny: Tom Cruise is returning to Oprah. And this time, at least half the show will be outside the studio, presumably to limit the chances that any couch-pummeling hijinks will occur.

The show is meant to celebrate the Scientolofreak's first role in "Risky Business" 25 years ago, and he will do one part in-studio, and one part at his Telluride mountain retreat, as MSNBC first reported. Unclear if there are any couches in that house, or if the Bride of LRH and the Scientolotot will appear.

Miley Cyrus got a little support yesterday from one of her stablemates in the Disney fold: Brenda Song tells People that what MiCy does in her personal life is ok by her.

"She brushes everything off with a smile. She is truly a diva – in a very good way!" says Song. And how is being a diva ever a good thing? TMZ discovered that Song had a little saucy moment of her own when a snap of her showed up in a backpages sex ad in an L.A. paper.
