Katharine McPhee & Megan Hilty: Red, White, & 'Smash'!

Smash co-stars Katharine McPhee and Megan Hilty show off their patriotic sides on the eve of the Fourth of July!

Katharine performed at the unveiling of a larger-than-life, 6,000 square foot rendition of the American Flag sponsored by Tide at Bryant Park on Tuesday (July 3) in New York City.

Megan rehearsed that afternoon for her performance on A Capital Fourth, PBS’ Independence Day celebration airing live tomorrow night (July 4) from the West Lawn of the U.S. Capital in Washington, D.C.

FYI: Katharine is wearing Theonne‘s light pink silk draped blazer.
