Holly Madison was a vision in pink as she cut an appropriately colored ribbon to introduce Pinktober at the Hard Rock Hotel Friday. Radar Online has all the pictures.

The former Girls Next Door star who now has her own Sin City-based show, Holly's World, Madison will be appearing at several events all month long as she helps promote Breast Cancer Awareness Month, Vegas-style.

Making her way around town on what was a pleasant day, Audrina Patridge was spotted dropping by a flower Store in West Hollywood on Wednesday afternoon (October 7).

Wearing a t-shirt that says “Know Your Girls” in support of Breast Cancer Awareness, the MTV reality starlet was in a cheerful mood as she picked up a bouquet while paparazzi eagerly snapped up shots.

Meanwhile, Miss Patridge came up during a recent interview with her Hills co-star Kristin Cavallari - with Miss Cavallari telling MTV News that she isn’t dwelling on their ongoing feud.

Kristin tells, “I’m over it. I never had an issue with her. I think she’s the one that has an issue with me, so I’m cool. I’m over it.”
