Openly gay actors Jane Lynch, Neil Patrick Harris, Lily Tomlin and Alan Cumming are nominated in Saturday's Creative Arts Emmy Awards.

The Creative Arts Emmys honor many of the behind-the-scenes categories such as costumes, lighting and make-up, but it also includes the guest performance category.

An openly gay actor has been nominated in each of the four guest spot categories, opening up the possibility of an all-gay sweep in the guest category today at the Nokia Theater in Los Angeles.

Gay-dad-to-be Neil Patrick Harris, who plays heterosexual sex hound Barney Stinson on CBS' How I Met Your Mother, is nominated in the Outstanding Guest Actor in a Comedy Series category for an appearance on Fox's Glee. And Jane Lynch, who plays sharp-tongued coach Sue Sylvester on Glee, is nominated in the Outstanding Guest Actress in a Comedy Series category for an appearance on CBS' Two And A Half Men.

In the drama department, Lily Tomlin is nominated in the Outstanding Guest Actress category for her work on FX's Damages, while Alan Cumming is up for an award in the Outstanding Guest Actor category for an appearance on CBS' The Good Wife.

They face stiff competition from big names, including Betty White (for her appearance on Saturday Night Live), Jon Hamm (30 Rock), Kristin Chenoweth (Glee), John Lithgow (Dexter), Tina Fey (Saturday Night Live) and Ted Danson (Damages).

The three-hour ceremony won't be televised live, but cabler E! will broadcast an edited version on Friday.
