It's the latest celebrity craze/impossible standard — losing all your baby weight the instant after giving birth. It’s ridiculous. And Kristin Cavallari isn't having it.

The Hills and Dancing With the Stars Season 13 alum just showed off her adorable 6-week-old son, Camden Jack, and Us Weekly jumped in to quote a source who said Kristin had already lost all her baby weight.

Well, that's news to Kristin — and another reason it's not always good to believe unnamed "sources." Kristin tweeted in response, "I haven't lost all of my baby weight yet. Thats sending the wrong message to women.” She also tweeted a link to a Life & Style interview, in which she acknowledged she's "struggling to lose the last few pounds that I have but I am happy with my weight and I'm not going to kill myself for it."

It's good of her to clarify, so no new moms — or potential moms — feel defeated by another impossible celeb standard. Most "normal people" don't have the time or money for personal trainers, nutritionists or nannies to watch the baby as they work off the weight. It's good when some stars show that it's not always a picnic for them either, even with an easier road to fitness.

Dancing With the Stars Season 15: All-Stars will premiere on Monday, September 24 at 8 p.m. ET/PT on ABC. Check out the full All-Stars cast list here.
