It took her long enough, but the eldest spawn of Bruce Willis and Demi Moore is finally putting her pedigree to good use. Rumer Willis reminded the world of her burgeoning acting career at last week's premiere of From Within, the horror flick she's starring in, and was spotted posing for her first ad campaign for Wal-Mart's newest surfer fashion brand OP (formerly Ocean Pacific). And while the extensions she wore for the premiere coupled with the bikini body she displayed alongside Pete Wentz for the photo shoot do admittedly evoke memories of a younger version of her iconic mom, are Rumer's recent career choices really going to jumpstart a Demi-like fame trajectory? Or will she soon be on MTV's third season of Rock The Cradle?
