Cher, Pauley Perrette, Chely Wright and Joy Behar were among the celebrities tweeting about the anti-gay rhetoric at Saturday's GOP debate.

The debate, held at St. Anselm's College three days before New Hampshire holds the nation's first presidential primary, included Mitt Romney and Newt Gingrich reiterating their opposition to gay marriage.

“The unbelievable homophobia being spouted by the republicans at the #NHdebate is making me physically nauseous & cry. Awful,” NCIS co-star and gay rights ally Pauley Perrette messaged to her more than 221,000 followers.

Joy Behar, a co-host of ABC's The View, tweeted: “Why is thrice married adulterer lecturing on the sanctity of marriage? Gingrich is the biggest hypocrite on this.”

Country music singer Chely Wright, a North Carolina native who is opposed to a proposed gay marriage ban in the state, sent out a tweet directed at Rick Santorum, whose outspoken opposition to gay rights hasn't gone over well in liberal New Hampshire: “Dear Santorum, It's not just the 'gay community who'd like to change laws' to grow equality. There's a group of folks called straight allies.”

And singer Cher retweeted a tweet from @itaitantuboo: “My partner and I are watching the NH debates and we are pretty much disgusted at comments made!”
