Globe (December 14, 2009) has its ongoing "Who's Gay and Who's Not in Hollywood" feature. Here's the tally, according to them: 

Derek Hough: A source says not, but an anonymous Internet commenter says, "He is GAY!"

Rush Limbaugh: Had NEVER heard this one, but allegedly there have long been rumors about his being gay. A picture of him being kissed by drag queen (out of drag) Elaine Lancaster is used. They say no.

Neil Patrick Harris: Duh.

Kelly Clarkson: They say she dresses like Chaz Bono and only minds being called gay "when people throw it at me to be slanderous."

Jessica Biel: Her famous ass-grabbing pic with a woman is shown and rumors about her with women are highlighted. "Biel insists she's straight."

Simon Cowell: They say no.

Rob Pattinson: No.

David Ogden Stiers: Yes.

Dean Sheremet: They seem sympathetic to the yes side while saying a pal calls the rumors "vicious."

Jaason Simmons: Yes.

Derek Jeter: They seem to intimate that it's a yes, but won't confirm.

Will Smith: They say no.

Cher: No.

Fergie: She's bi.

Dolly Parton: Same old fuckin' story about Judy Ogle.

Anderson Cooper: Pic of him with his boyfriend Ben Maisani and a rumor that he may come out soon.

Martha Stewart: Intimations, nothing solid.

Michael Urie: Repeats rumor about him being mad about being called out. Bizarrely, they state he is an avowed heterosexual who was once in a long-term relationship with a female singer. Um, no.

Angelina Jolie: We all know she'd fuck anyone hot.

Eric Stonestreet and Jesse Tyler Ferguson: No and yes, in that order.

Queen Latifah: Pic of her with her lover, but quote of her denying she's gay.

John Mayer: Innuendo, and they show he carries a pink phone.

Christina Applegate: She once married a woman, but it wasn't consummated.

Kenny Chesney: Repeats his boasts of bedding hundreds. Of women.

Oprah & Gayle: Probably.

Ryan Seacrest: They flirt with it but point out his "relationship" with an actress.

Wanda Sykes: Yes.

Barry Manilow: Thinly veiled yes.

Ken (Barbie's boyfriend): I had never heard this, but Ken was modeled after the son of Mattel's founders, grew up haunted by being named for a genitalia-challenged doll, married, had kids...and died of AIDS in 1994, a closeted gay. Bizarre.
