Amanda Seyfried is the latest celeb to debut a "lob" (aka a long bob)!

The Ted 2 star came straight out of the salon with her gorgeous blonde hair cut short on July 29. Turns out, the motivation behind her new look was the non-profit Locks of Love, which makes wigs for sick children.

The 29-year-old also took to Instagram to share a photo of her beloved dog Finn rocking her chopped tresses (sooo cute!)
