Carter was born in Phoenix, Arizona. She is of English, Mexican, Irish descent. Carter made her public television debut on Lew King's Talent Show at age 5. During high school, Carter performed in a band called Just Us, consisting of a marimba, a conga drum, an acoustic guitar, and a stand-up bass played by another girl. When she was 17, she joined two of her cousins in another band called The Relatives. Actor Gary Bu was the drummer. The group opened at the Sahara Hotel and Casino lounge in Las Vegas for three months; because Carter was under 21, she had to enter through the kitchen.
She played herself on the show. She knew the Schmidts and had seen Walden growing up. She expresses interest in Walden, but ends up having a threesome with Jenny and Robin.
