Alexandra Breckenridge isn’t chalking her post-baby look up to magic.
The actress, who plays Kevin’s love interest Sophie on This Is Us, opened up to PEOPLETV on the 2018 Screen Actors Guild Awards red carpet Sunday about attending after giving birth to daughter Billie six weeks ago.
“I just had a baby six weeks ago. I can’t take credit for any of this — it’s totally genetic,” admitted the star, 35. “I’m feeling good during the day, but I’m also exhausted. My baby keeps me up until about 4 in the morning.”

Breckenridge adds, “It takes a large team of people to put me together this well because I definitely don’t look like this when I wake up.”
The actress and husband Casey Neil Hooper welcomed Billie on Dec. 6, and shared her first adorable photos with PEOPLE. They are also parents to a 16-month-old son named Jack.
