Happy 4th of July from Katharine McPhee

Katharine McPhee is spending her 4th of July soaking up some sun on a red, white, and blue towel in a bikini. “Be cool,” she wrote on Instagram.

This is Katharine’s last day of relaxation. She heads back to the set of Scorpion tomorrow to begin work on Season 3!

Scorpion Season 3 returns to CBS on October 3rd with a special 2 hour premiere.

Be cool. #happy4thofjuly ✌🏼
