Looks like Audrina Patridge‘s enhanced bosom isn’t just good for getting guys’ attention. The reality star used them as a bouncing billboard yesterday — to promote breast cancer awareness, of course — while shopping for flowers in L.A.

Audrina, whose family has been personally touched by breast cancer, is helping to bring attention to the disease during Breast Cancer Awareness Month by taking part in Yoplait’s new “Know Your Girls” campaign.

If you want to help, visit Facebook.com/YoplaitPledge, where young women can pledge to join in the campaign and take an active role in their breast health.

For every pledge received by Oct. 31, Yoplait will donate 10 cents to Susan G. Komen for the Cure, up to $100,000.
