Celebrities aren't immune to the lure of hashtags. For every one of your BFF's #TBTs, Kate Hudson has one that blows an old vacation trip out of the water. So, it makes sense that the stars went all out when it came to the #10YearChallenge that swept Twitter and Instagram.

Just like you, they had eyebrow regret and some questionable hair choices, and they took some time to poke fun at themselves. Remember, while stars really are just like us sometimes, not everyone has a record of their time on the red carpet. Thankfully, they do — and we're glad that they're good sports about the late '00s nostalgia.
