It wasn't the prelude to Rick Santorum's official presidential announcement that he likely expected: Actresses Miley Cyrus and Keira Knightley joined MSNBC's Rachel Maddow in giving the beleaguered Republican more bad press.

Santorum, who is expected next week to become the seventh Republican candidate to officially enter the race for the GOP presidential nomination, cannot seem to escape his Google problem.

The problem is simple. In 2003 the former Senator from Pennsylvania likened gay unions to what he called the moral equivalent of “man on dog,” angering gay activist Dan Savage. Savage, also the editor of Seattle alternative The Stranger, asked his readers for a new definition for “santorum” and then posted it on a dedicated website which has risen to the top of the search giant's results.

“Mr. Santorum's name recognition is so low that this Google thing presents a serious barrier for his campaign,” Maddow said on her program Friday. “Voters meet him, they shake his hand, they want to know more, so they go home, they Google him – and ack! dude let go of my hand.” (The video is embedded in the right panel of this page.)

Cyrus also took a swipe at Santorum, linking his campaign to clothier Urban Outfitters in a tweet to her more than 1 million followers: “'IF WE ALLOW GAY MARRIAGE NEXT THING U KNOW PEOPLE WILL BE MARRYING GOLD FISH' – Rick Santorum UO contributed $13,000 to this mans campaign.”

When messaged back, “@MileyCyrus what happened to that Christian girl from TN with descent moral values and a lot of heart?” the teen pop sensation responded, “what an ignorant statement. I don't have 'alot of heart' cuz im not gonna be a closed minded hypocrite? LOVE IS LOVE. GOD IS LOVE.”

During a May 9 appearance on Comedy Central's The Daily Show, Knightley said Googling Santorum had taken away her innocence, referring to the search engine's top result that redefines the meaning of “santorum.”

Host Jon Stewart asked whether that would hurt Santorum's chances at winning the Republican nomination.

“Maybe that's a great thing,” Knightley responded.
