Not quite ready to tie the knot herself, Amanda Bynes looked more than content playing the role of bridesmaid during a Saturday afternoon (July 26) ceremony in Simi Valley, California.

Celebrating her big sister Jillian’s nuptials, the 22-year-old Hairspray actress looked lovely in a flowing gown as she followed her sis down the aisle with two bouquets of flowers in-hand.

After the ceremony, Amanda made a point to make sure that her sister didn’t have any food stuck in her teeth as the two readied for what was surely a grand reception.

As for her career, you can see Amanda back in action on TV this October alongside Harry Connick Jr. and Angie Harmon on the new TV series Living Proof.

The Dan Ireland directed drama tells the story of “a doctor who devotes his life’s work to finding a cure for breast cancer.”
