Red Carpet Roundup: Mandy Moore and Drew Barrymore are flawless in floral editors

A handful of stars left us wanting more after seeing them on the red carpet this week!

Mandy Moore and Katharine McPhee led the pack at the SAG-AFTRA Foundation Patron of the Artists Awards on Thursday night in their respective red carpet looks. 

Moore sizzled in a crimson, tiered Johanna Ortiz gown with a plunging neckline and form-fitting silhouette, while McPhee dared to bare in a black ensemble with a lace bodice that she paired with a black tailored jacket.
