It's no secret that Ashlee Simpson has gotten plastic surgery in the past — but recently, it appears the 32-year-old underwent another makeover! "She looks like a glamorous Hollywood starlet,” plastic surgeon Dr. Anthony Youn, who hasn't treated the singer, told Life & Style.

But cosmetic dermatologist, Dr. Tabasum Mir, expressed concerns over her appearance: “She needs to be careful with the Botox! I’ve seen pictures where her eyes look frozen." The blonde beauty first sparked plastic surgery rumors in 2006 after the bump on her nose
conveniently vanished. “Surgery is a personal choice,” she said at the time, neither confirming nor denying that she went under the knife.

Scroll down to see what procedures our experts think she's tried out since.

Eyebrows

Dr. Youn believes she had work done on her eyebrows. “Her eyebrows are fuller and lifted,” he said, “possibly from a filler like Restylane Silk.” The price for the procedure is estimated at $1K.

Cheeks

The singer has more defined cheekbones now, Dr. Alexander Rivkin observed. “It looks like she may have used a subtle filler like Voluma, which lasts up to two years." The price for the treatment is $2.2K.

Nose

Dr. Rivkin thinks her alleged 2006 nose job cost anywhere from $7K to $10K, and could use an update: “It appears she’s experiencing cartilage collapse one-third of the way down.”

Lips

“Her lips look more voluminous,” Dr. Mir said. “But it looks good, she didn’t overdo it.” Lip fillers cost between $800 and $1K per round of injections.

While remaining coy on the topic of surgery, Ashlee has said in the past that she's very happy with herself. "I don’t get bothered by people saying what they say. I’m a happy person, and I’m happy with my looks," she shared. "Everybody always has an opinion. One minute they’ll love you; one minute they’ll hate you. When you go home to sleep at night, [the important thing] is to feel good about yourself. And I do."
