"She looks so different in this picture! The lips maybe?" wrote one, while a second agreed: "Definitely the lips. She looks so pretty au natural," and a third wrote: "I think she may have had her lips done."
Some of Julianne's fans mistook her for another gorgeous celebrity and commented: "You look beautiful, you have Sofia Vergara vibe in this pic, maybe it's the hair?" and, "I thought it was Sofia Vergara when I first scrolled to this pic. Then did a double take when I saw it was Julianne."
Julianne got fans talking with her glamorous makeover
Julianne didn't address her new look but captioned the photo: "Happy Monday. What’s one thing you are grateful for today? I'm grateful for my health.
"My physical, mental, emotional and energetic health. It's amazing how when one of those things is not healthy, it can be a ripple effect for the others.
"Sometimes it’s out of balance and that’s ok, just keep trying to even it out by shifting your focus where it needs some extra care and support. Sending you all love and good energy."
