Britney Spears hit up designer Christian Audigier warehouse yesterday for a swagfest! The designer, best known for his Ed Hardy clothing line, invited Brit to take whatever she wanted, and the pop mom was happy to oblige!

"Thanks, Ed," Britney told Christian after he handed her a belt, as seen in this video from X17online.com. It seems that Spears is unaware that Ed Hardy is just Christian's clothing line, not his name.

Momma Lynne accompanied the under conservatorship pop star. It seems Britney had younger sister Jamie Lynn on her mind when she asked if Audigier could send the pregnant "Zoey 101" star some clothes for her 17th birthday (which is today), and for the baby.

As they left, a thankful Britney posed with a fan and watched as staff stuffed her SUV with mounds of clothes. Hopefully, Audigier threw in some free panties.
