That's so sad. She was real cute.

So sad

Really sad, way too young. RIP

She also had the challenge of playing the least liked character on Buffy

woah.

Also she's 39? Man I'm old.

I only ever saw her in Euro Trip - and she was cute there.

Terrible, I grew up with her shows/movies. Apparently she just had a liver transplant.

We were the same age and I'd been watching her since the Nickelodeon days. I recall seeing a video of her from a few years ago and something seemed off, but I'm still kind of shocked by the news.

Followed her on Instagram and yeah, she was looking rather gaunt. Missed out on getting an autograph at the 10th anniversary screening and Q&A of Euro Trip.

Oh this is terrible. I loved her post Buffy, she was so cute. I saw her on Wheel of Fortune a couple of years back and she hadn't lost anything. Sad news.

Geez, that’s sad. My kids loved Ice Princess so I’ve watched that way more times than I can count. I watched Buffy too.

Aw, man, that's really sad to hear. She was great in Buffy, Eurotrip, and The Ice Princess. Several years ago I saw her in a Hallmark-type Christmas movie and she looked pretty different, had gained a lot of weight. I wonder if that was related to her medical condition.

I never watched Buffy or Gossip Girl but I did see her in Eurotrip. She was definitely a cutie in that.

Very sad news. So young. I watched Gossip Girl and saw a lot of her appearances through the years. Not a star, but a consistently working actor. Sad that she had the health problems.

I just looked at Michelle’s Instagram. The most recent picture she posted of herself was February 12. And yes she did look gaunt.

Wow, I think this is the first time I've been shocked to see one of the RIP threads pop up.

She's on Buffy and Eurotrip right now. I literally just clicked on Eurotrip this minute and it is her bikini at the beach scene.

Such a beautiful woman, she was.

First Buffy cast member to pass.

Given the weight loss, I would think she was sick, but she said she was not. I am honestly curious what the cause of death is.

That is so sad. I loved her on Buffy and that is way too young.

She had a liver transplant last year. It was known she had substance abuse issues. It's looking like maybe the liver was rejected by her body.

Guess I picked the wrong link to click. The People story did not mention the liver transplant.

Same here, Eurotrip is the only thing I ever saw her in. Sad news though, way too young.

I only knew her from Beautiful Ohio, but my wife was a big Buffy fan.

Far too young...

RIP

Aside from Buffy, she was a great villain in Gossip Girl. RIP

I just saw this. Wow. I had a huge crush on her when she grew up.

Definitely a shock to hear. Watched her on Buffy back in the day. Didn't know she was having health problems.
