Ever think that Lauren Conrad is too picky about guys? Maybe it's due to the awful pickup lines that The Hills star has been subjected to!

"The pickup lines have become so cheesy, people hear them as a joke now," Lauren Conrad, 21, says in the new issue of Us Weekly (cover below).

Some of the worst lines LC has heard?

"A guy the other day said, 'You're a really smoking babe and I think you should call me,' and handed me his number," Conrad says, adding that, "I just wonder if that's ever actually worked. I mean, 'Smoking babe'?"

It gets worse.

"I had a guy come up to me and ask for a Band-Aid and I said, 'No, I don't have a Band-Aid.' Then he said, 'You're supposed to ask me why,'" she says.

When the ever-friendly Lauren Conrad played along and asked the guy, the pickup artist replied, "Because I scraped my knee when I fell for you." Gag. LC recalls, "I didn't understand it. I was like, 'Did you really fall down?'"

Lauren Conrad: Not immune from the lame lines.

Still, The Hills star realizes it can be intimidating for anyone - even a celebrity such as herself - to approach members of the opposite sex.

She admits, "I've pretended to know a guy before" in order to get his attention. "I actually said, 'I think I know you from somewhere.'"

Adds Conrad, "It's hard to walk up to someone out of nowhere and be like, 'Hi, I'm Lauren.'" Feel free to try it with us anytime, girl. We have a good feeling.
