They come in pairs, sometimes in threes or more, wearing such items as "Winning" T-shirts and tiger-striped leggings, professing their love for all things Charlie Sheen.
"If he wants us to come and show our tiger blood, I'm going to support Charlie," said Erica, who drove down from Ontario, Canada, with her friend Heather to catch Sheen's first show in Detroit. "I support him one hundred percent. I'm on a drug, and it's called Charlie Sheen. You're bi-winning, Charlie!"
The former "Two and a Half Men" star is a pop culture sensation, yes, but he's also a thrice-divorced man with a history of domestic violence who's dating two adult film actresses he calls "the goddesses." Yet, women flock to him.
Paris Hilton bought into Sheen-mania last month, tweeting "Hey Neighbor, I think I might have #Tigerblood and I'm definitely #Winning! Huge!" (That was four days after authorities invoked a restraining order from Sheen's estranged wife, Brooke Mueller, and removed their twin boys from his home.)
Kelly Preston followed Hilton's lead. In March, the actress, who was engaged to Sheen before he shot her in the arm in 1990, told reporters, "He's such a good person underneath all of it, he really is."
This week, Miley Cyrus said she rejoined Twitter partly because of Sheen.
"Do not fear... the Sheenius is here!," she wrote Sunday, invoking one of Sheen's many catchphrases. "I'm not gonna lie. I came back to twitter for 2 reasons," she continued. "My fans and to follow Charlie Sheen."
When Sheen tweeted "Always felt you were epic! Now you proved it! Thanks for the love," Cryus tweeted back, "You have taught me everything I know about WINNING. Duh!" On Monday, tweeting while making dinner, she noted, "There's only one thing missing & that's Charlie Sheen!"
Sheen's nonfamous female fans seem similarly smitten with him. Before Saturday's show in Detroit, many flaunted the outfits they donned for the occasion -- Erica and Heather made tiger-striped leggings and wore T-shirts adorned with metallic tiger cubs.
"I'm hoping Charlie will find us and make us his goddesses," Erica said. Heather chimed in, "Yes that's it, he's going to pick us up, he's going to take us on his next trip."
But when asked about Sheen's arrangement with his "goddesses" -- Natalie Kenly and Rachel Oberlin -- and his custody battle with Mueller, some women seemed at a loss for words.
"I don't know, I don't know. I don't know what to think about anything that he says," said Melissa Shovlin, who came from Fort Wayne, Ind., to see the former "Two and a Half Men" star. She and her friend Haley Clark wore matching lime green T-shirts plastered with the Sheen mantra "Winning!" on the front and "Duh!" on the back.
"I have a son, and I can't even imagine putting him through that," Shovlin said about the Sheen-Mueller custody fight.
As most Sheen followers know, the actor bombed in that first Detroit show; he practically got booed off-stage. Still, some of the women stood by their man.
"We do still love you Charlie. Your goddesses are beautiful. We're here for you if you need backup," Erica said. "Charlie, if you need any help, you come see us, babe."
