Jessica Lowndes vs. Adrianna Tate-Duncan
"We couldn't be more opposite," she said. "I've never been to rehab. I've also never had a baby."
Watch the video above to hear Jessica talk about what it's like to share a music career with her on-screen character. She also revealed that they do have similar fashion tastes and are particularly in love with vintage and Old Hollywood inspired style. But that's where the similarities end.
"Personality-wise, my character -- especially in season three -- was very manipulative and has a very dramatic personality," she said. "Whereas me, I don't really know how to be mean. I love helping people and I like keeping a pretty mellow life outside of the show."
Jessica left our shoot to go film a new episode of '90210,' which airs on The CW on Tuesdays.
