Los Angeles, April 8 – The biggest buzz at the delightfully named “What a Pair” breast cancer fundraiser wasn’t about the duets performed by icons like Deborah Gibson, Cheryl Ladd or even ‘80s chart topper Taylor Dayne. All eyes were on honoree Renee Zellweger, who has gone back to blonde after stints as a brunette, and more recently, a redhead. The actress remains super buff after losing her Bridget Jones pudge. Zellweger’s publicist, Nanci Ryder, a breast cancer survivor, was also honored at the event. Desperate Housewife Nicollette Sheridan didn’t perform, but she and fiancé Niklas Soderblom made a nice pair.
