At a premiere party at the Spanish-colonial-style Bel-Air Bay Club for the new Lifetime show "Devious Maids," the center of attention was not the five actresses who play the lead characters, Latina maids who cook, clean and scheme while looking after wealthy white families in Beverly Hills.

Instead, the spotlight fell on one of the executive producers, Eva Longoria, better known for her own role as the wealthy Gabrielle Solis on "Desperate Housewives." She worked the room like a politician, making grand introductions punctuated by a bright smile and a hug and a kiss on the cheek, and holding barely audible conversations.

Her biggest priority was to check in on each of "the girls" - as she called the five actresses - to see how they had fared on the red carpet. Nine years ago Longoria was a young, relatively unknown actress in the cast of "Desperate Housewives." But then she changed the script, positioning herself as a Hollywood power player on Latino issues and a highly regarded political advocate.

Now she finds herself in a position of having to defend her latest project against critics who say the show relies too much on the cliché of the Hispanic maid.

"When people talk about stereotypical maids, these maids are anything but," Longoria, 38, said over a long lunch at the Chateau Marmont in West Hollywood two days before the premiere party. She said future plot points would reveal more developed people.

She was eager to counter the negative reactions to the show.

"I think it's important for us to have a dialogue of identity in our culture, and even though this show may not be your experience, it is a lot of people's experience," she said. Latinos, she added, " over-index in domestic workers: That is a fact, that's not an opinion."

The ratings for the premiere of "Devious Maids" were modest. Going up against the season finale of AMC's "Mad Men," the show attracted 2 million viewers, slightly below the Lifetime show that preceded it at 9, "Drop Dead Diva" (2.2 million).

Longoria's rise as a media force has been paralleled by her political ascent. She stumped for President Barack Obama in 2012, helping round up critical Hispanic voters, and she was a founder of the Futuro Fund, which raised $32 million for the campaign. She recently spoke at the Clinton Global Initiative in Chicago; left a few days later for Colombia to film a documentary for the Half the Sky Movement, an international women's advocacy group; and signed on to a fundraising drive for the political group Battleground Texas, whose goal is to raise money to "put Democrats back on the map" in the state, in the words of her message on the group's home page.

And in May she completed a master's degree in Chicano studies from California State University, Northridge.

"I'm a little in awe in terms of how she's transformed herself," said Marc Cherry, an executive producer of both "Devious Maids" and "Desperate Housewives," who cast Longoria in 2004. "She was just an actress that had done a couple of prime-time shows and had done some daytime."

Before its debut, the criticism of "Devious Maids" included an open letter in The Huffington Post from Michelle Herrera Mulligan, the editor-in-chief of Cosmopolitan for Latinas, who called the show a "wasted opportunity." (Longoria had been on the magazine's spring cover months before Mulligan's letter was published online.)

Alisa Lynn Valdes, a former journalist and author of the novel "The Dirty Girls Social Club," wrote a critical online opinion piece on NBCLatino.com about the show.

"It is not wrong to be a maid, or even a Latina maid," she wrote, "but there is something very wrong with an American entertainment industry that continually tells Latinas that this is all they are or can ever be."

Most maids, however, don't sleep with their bosses. The show's first episode begins with a whopping , albeit campy1 , dose of classism, with an employer threatening to deport her maid for having sex with the employer's husband.

"They are five strong, female, Latina characters, so it's like the three hurdles we had to overcome to get this on the air in Hollywood," said Longoria, who added that the show also has two Latina writers out of five. "You're never the lead, then if you are the lead, you are usually a lead that services the main character, which is a white male actor."

The executive producer Cherry said he called Longoria early on as he was considering making the English version of a Mexican telenovela, "Ellas son ... la alegría del hogar" (literally, "They Are ... the Joy of the Home").

"I know that eyebrows are raised when a middle-aged balding white guy decided to write a show called 'Devious Maids' - I get it," Cherry said, adding that Longoria gave him her blessing to do the show with an all-Latina cast and is sent cuts and script drafts from each episode.

Longoria used her political clout and organizational ties for the show, which has garnered support from major Latino advocacy groups, including the Mexican American Legal Defense and Education Fund, the National Council of La Raza and the National Hispanic Media Coalition, a watchdog group for diversity in media.

"At some point she blossomedinto this spokeswoman for the Latin community, as someone who was involved in political issues, meeting the president, going to the White House," Cherry said. "I became super impressed with her decision to lead a more meaningful life than your typical Hollywood actress."

Longoria has two shows in development, one about a Latina mother-and-daughter law firm, and another about two Hispanic politicians. "We are touching every part of the machine," she said. "And yes it's about giving opportunities. Who else is going to open the doors, who else is going to write these stories?".
