In the wake of the California Supreme Court's decision on Tuesday (May 26) to uphold Proposition 8, which banned same-sex marriage in the state, Hollywood celebrities have been voicing their opposition to the ruling.

On her Twitter account, ex- Danity Kane member Aubrey O'Day posted a picture of her dog — which she says is gay — dressed in a rainbow pride flag and a pink headband and sporting a sign saying "Love for all."

"Pass this on!" O'Day wrote. "Love doesn't discriminate, love is even for puppies! No on Prop 8!"

Kim Kardashian posted a reaction on her blog. "I thought we were more forward thinking than this, and I'm disappointed in the Supreme Court for being so closed minded," she wrote. "Everyone ... gay, straight, bisexual, transgendered, everyone should have equal rights to marry who they want to. I have many gay friends and all I want is for them to be happy, yet this is just another obstacle in their way. Now they must continue fighting to be granted a basic civil right that many people take for granted."

Former 'NSYNC member Lance Bass released a statement to "Access Hollywood," saying, "I can only hope to one day live in a country that grants equal rights, opportunity, and freedom to all citizens."

Lindsay Lohan's ex-girlfriend, celebrity DJ Samantha Ronson Tweeted: "Nice work California court, u must be beaming with pride. Bet ya can't wait to tell the grandkids one day all about how you saved marriage!"

Also on Twitter, Demi Moore said, "I am deeply saddened by CA courts decision over Prop 8, there's no room 4 judgment it only creates separation & I'm pretty sure we R all equal in God's eyes. Luv is luv in whatever form!"
