Jennifer Garner: Baby Bump at Pink Party!

Jennifer Garner shows off her growing baby bump in YSL as she arrives at the 2011 Pink Party held at Drai’s Hollywood to benefit Cedars-Sinai Women’s Cancer Program on Saturday (September 10) in Hollywood.

The 39-year-old pregnant actress hosted the event, which raises money and awareness for gynecological and breast cancer research.

Jennifer is a frequent attendee of the annual event! She was a guest at both the 2008 and 2010 parties.

Earlier in the day, Jen spent time with her daughters Violet and Seraphina and took them both to a ballet class.

FYI: Jen finished her look with Valentino shoes and David Webb jewelry.
