AnnaLynne McCord Without Makeup and Other Celeb Twitpics of the Week

“I woke up this morning and decided I'm over Hollywood's perfection requirement. To all my girls (and boys) who have ever been embarrassed by their skin! I salute you! I'm not perfect - and that's okay with me!” tweeted AnnaLynne McCord, daring to bare her face without makeup on Twitter. (Teensy) blemishes, untamed mane and all, she looks pretty gorgeous.

AnnaLynne McCord wasn’t the only one showing off her behind-the-scenes beauty on Twitter this week: Karolina Kurkova shared a beauty secret. “It's on always glamorous!!!” tweeted the model.

Not sure whether this is a style or a disguise, but Demi Moore posted a pic to her new, post-Ashton twitter account (no longer @mrskutcher). “Feliz Cinco de Mayo!” she tweeted, wishing her followers a fiesta.

The “world’s hottest mom” showed off an early Mother’s Day present to herself, a nameplate necklace reppin’ daughter Blue Ivy, which she wore in a pic posted on her Tumblr.

“Visited @seventeenmag yesterday! Had so much fun,” tweeted Kendall Jenner who will be the magazine’s newest West Coast fashion contributor along with sis Kylie.

Jessica Alba celebrated her 31^st birthday with a new (old) piercing. “Getting my second pierce repierced!” she tweeted.

Heidi Klum shared a picture from when she was a fresh-faced teen model (who, legend has it, got rejected by Michael Kors on a go-see). “So long ago... test shoot at 19 years old!” tweeted the supermodel.

Gwen Stefani returned to her roots this week, rocking out with No Doubt, who have an album in the works. “@gwenstefani preparing for the 'addicted to love' video auditions,” tweeted her bandmates.

Floral is all over—even on nails! “My fingers are in FULL bloom today!” tweeted Katy Perry, who is known for her out-there manicures. This one looks a tad impractical.

Lady Gaga posted a pic for her followers wearing what looks like one of those scrunchies made out of fake hair. “Goodnight lil' babies...i lubbs yous xxx,” she tweeted. What do you think--is it the next hot accessory?
