We'll be the first to say red lipstick can get a little stale, but apparently not if Cameron Diaz is wearing it. The star of the new summer comedy, 'Sex Tape', stepped out late last week for the movie's Los Angeles premiere, and we instantly noticed her makeup.

Cameron chose a deep shade of matte tomato red, making her blue eyes really pop. When choosing a shade of red, it's important to take in all the important factors -- you know, like skin tone and hair color -- before making the final decision. With bold orange and hot pink lips trending, it's nice to see a celebrity like Cameron embracing a more traditional, yet still vibrant and pretty color. Translation: We can totally see anyone wearing this shade of red.

To get Cameron's look, we highly suggest consulting the associates at your local department store beauty counter to ensure the perfect lipstick match for you skin tone, but if you want to have fun and test it out first, try this one in Mandarin Oriental by Estee Lauder.
