Kate's Glow?

“Kate’s fixated on Sienna Miller’s skin,” a source allegedly close to Kate Middleton tells Life & Style.  “She read in an article that Sienna uses a range of products from celebrity dermatologist Dr. David Colbert, so Kate ordered the whole skin care line for herself!” We don’t blame the Duchess of Cambridge for coveting Sienna’s flawless face.  The ColbertMD Daily System retails for $537 for five product set, www.colbertmd.com
