Colbie Caillat has gone from an underground hit on MySpace to a chart-topping star with her hit, "Bubbly."

Now she's looking for a special someone to crinkle her nose as she joins "Extra's" list of America's most eligible bachelorettes!

She’s the beautiful brunette beauty taking Hollywood by storm. Now Michelle Ryan, otherwise known as the Bionic Woman, is one of “Extra’s” most eligible bachelorettes.

So how does she keep up with the intense stunts on set?

“I do pretty much my own stunts,” she said.

And when it comes to dating, she’s an old-fashioned girl.

“Flowers, chocolates, jewelry – those kinds of things,” she admitted.

Right now, Michelle is devoting 16 hour days on the Vancouver set of her new show.

“I’m really having the best time,” she said.

But there’s always time for romance!

“I’m very picky,” she confessed. “I’m good at playing hard to get.”

Jackie Warner stars in her own reality show on Bravo, owns one of the most famous gyms in Hollywood, has her own line of clothing and is the picture of physical perfection. No wonder she doesn’t have time to meet someone special!

Now the buff “Workout” star is sitting down with “Extra” to find someone who can get her pulse racing.

Gorgeous Victoria's Secret model Miranda Kerr strikes a pose as "Extra's" eligible bachelorette.

It's the moment so many men have been waiting for: the kickoff of America's most eligible women! And there's no better way than starting with Playboy's newest celebrity covergirl, Kim Kardashian.
