Kaitlynn Carteris laughing off the haters.

On Tuesday, theHills: New Beginningsstar, 31, shot down a commenter on Instagram who told her she looked “too thin” — reminding the troll that she’s “been through some s— lately LOL.”

So has the original poster’s gripe, which reportedly came on a recent bikini photo Carter posted, snapped as she lounged in a hot pink two-piece in Palm Springs.

“Oh Kaitlynn, you look too thin,” the user wrote. “Are you okay? You are so beautiful, hope all is okay. It was nice to see you healthy for a bit, modeling. It was normal. It seems like the new norm is being shown as super thin is only exceptional.”

Carter is coming off back-to-back breakups.

She and Brody Jenner split in August after a year of marriage, although they neverlegally wed. After their split, Carter quickly rebounded withMiley Cyrus, thoughthat ended just last month.

Cyrus, 26, — who began seeing Carter after splitting from her husband,Liam Hemsworth, 29 — is now dating Australian singerCody Simpson, 22. Meanwhile, Jenner is now dating 22-year-old modelJosie Canesco.

“I’m sure you’re going to see a lot of that,” Jenner toldETearlier in October, about his breakup with Carter. “Of course, you have to stay tuned to see what goes on with that. But, you’ll definitely see some of that.”
