Tricia Helfer and Felicia Day are among the celebrities joining the second season of Husbands, the web series which looks at a newlywed gay male couple

Husbands, which premiered online last fall, stars out actors Sean Hemeon (True Blood) as Brady Kelly, an out professional baseball player, and newcomer Brad Bell as Cheeks, an out actor. In season one, the newly dating couple heads to Las Vegas to celebrate the recent passage of a gay marriage law and wake up the following morning in a drunken stupor to discover they are a married couple.

Alessandra Torresani (Caprica, American Horror Story) plays Haley, the best friend.

Husbands is written and executive produced by Jane Espenson, whose credits include Buffy the Vampire Slayer, Caprica and the latest season of Torchwood.

According to Entertainment Weekly, the upcoming season, which premieres August 15, will include a bevy of guest stars, including Tricia Helfer (Battlestar Galactica), Sasha Roiz (Grimm), Magda Apanowicz (Caprica), Aasha Davis (Pariah), Clare Grant (Blake Snake Moan), Felicia Day (Dr. Horrible's Sing-Along Blog), Amber Benson (Buffy the Vampire Slayer), Emma Caulfield (Buffy the Vampire Slayer) and Dichen Lachman (Dollhouse).

Espenson said she received an overwhelmingly positive response from actors she contacted.

“My expectation was that I was going to be calling in favors, so I reached out to people I'd worked with and loved and knew were fantastic. Every one of them was eager to do it, but not just as a favor. They actually wrote back and said, 'Read the script, want to be involved.'”

Bell described the show's second season as “a commentary on television and what is considered entertainment and the double standard of certain groups of people.”
