The Modern Family star was snapped leaving the Today show studios in New York on Thursday (30 January) clutching her phone in her hands.
That gave us a good look at her case, which proclaimed: "Well behaved b*****s seldom make history." Naughty!
23-year-old Sarah - who plays Haley Dunphy in Modern Family - looked gorgeous in a monochrome dress and the same embroidered black coat she was wearing for the previous day of interviews.
She kept her hair loose and wavy (can we have the secret please to all her gloss and volume?!) and finished her make-up with a cute statement lip.
The actress is currently promoting new movie Vampire Academy, which is based on the bestselling book franchise of the same name.
Sarah was on Good Morning America earlier this week to chat about the movie, which opens in the UK in April. "I look very different," she said. "They put fake pimples on me, glasses. I loved it. I got to go to the set and not care what I looked like. She is very geeky."
The beautiful brunette's visit to GMA coincided with that of Rihanna, who was there to promote her latest venture: philanthropic partner to MAC.
Sarah joked on Twitter during the show: "So @rihanna just walked by my room at @gma. I started singing 'Stay' to her... She didn't."
However, she was later forced to clarify her tweet was, indeed, just a joke, after reports started claiming Rihanna had 'snubbed' her. "I find it funny people actually think my Rihanna tweet was real. She walked by my room. That's all. It's called comedy people :)."
