Last night I finally got around to watching “Youth Knows No Pain,” a new HBO documentary which aired on Monday night. The film is directed by Mitch McCabe, the daughter of a plastic surgeon, who has been obsessed with anti-aging treatments and products since she was little. Through interviews with various cosmetic surgery and beauty addicts, she explores our country’s obsession with never growing old. She puts her own weaknesses bravely on display and gets some seriously juicy and fascinating perspectives out of her incredible cast of “characters.” These include “lifecasters” Julia Allison and Mary Rambin, who are fond of fillers and Botox and come off as bratty and vapid; Allure Editor-In-Chief Linda Wells, who admits that her magazine pushes beauty products that don’t necessarily work but still make people “feel good”; Norman Deesing, who has spent more than 50K trying to look like Jack Nicholson; Erica Rose, a former contestant on “The Bachelor,” who is also the daughter of a plastic surgeon; and Sherry McCabe, featured in the clip above, who used to be obese. After she got gastric bypass and dropped a ton of pounds, Sherry got her whole face, tummy, and boobs done in an effort to look young and hot. She is pure sad amazingness. Check out the clip above and watch the full documentary, which is both eye-opening and entertaining, on HBO. [HBO: Youth Knows No Pain]

I’m a vegetarian, so it doesn’t take much animal cruelty to get me up in arms. But I always thought places like Sea World were havens for injured animals, which made me fully support them. Well, yesterday, I vowed to never visit another Sea World again after seeing the documentary “The Cove.” I feel tricked and lied to by all of the aquariums I’ve visited. Trust me, the animals you see there do not have “Free Willy” tales. Read on to see just how brutal the dolphin trade is. [Update: Found video that does not auto play, hooray!]

As “Grey Gardens” — both the documentary and the HBO film — proved, crazy cat ladies make good cinema. Debuting this week at the Silverdocs film festival in Washington DC, a new documentary, called simply, “Cat Ladies” hopes to capitalize on the popularity and cultural interest in the strangely endearing stereotype of a woman gone mad. While the one-hour film, which follows four ladies with a #&@$%-ton of felines (one has 123!), is supposed to reveal a “sensitive and emotionally honest portrait of women whose lives and self-worth have become intractably linked to cats,” it’s hard not to laugh or cringe in disgust at some of the women’s antics. Watch the clip above to see what I mean. [via TresSugar]

Even though model Sara Ziff has walked for Chanel and Marc Jacobs and has been the face of Calvin Klein, Gap, Stella McCartney and Dolce & Gabbana, she strips the modeling industry of its glamour like she’s ripping off false eyelashes. Mentorship from Twiggy? Coddling from Miss Jay?

Actually, the life of a professional pretty face means fending off a scuzz-load of pervy photogs, according to Sara’s documentary “Picture Me” about the behind-the-scenes of modeling.

• Annie “I Know UR Girlfriend Hates Me” Annie, who is known for disco as delicious as the pop of Chewing Gum, has a new single out.  Now normally we reserve a sweet spot in sweet release for full-on records, but this Berliners track record is so strong, we couldn’t resist. So get to steppin’ with Annie’s new single: “I Know UR Girlfriend Hates Me”. But seriously, how could anyone not like her?!

We’ve all heard sexuality is a spectrum and that there is a sliding scale of gay and straight.  While this has been the accepted perception, new evidence has come out that all women are gay. According to Dr. Meredith Chivers’ documentary entitled Bi the Way (trailer is above), pictures of naked men do nothing for the blood flow to women’s crotches.  While we could argue with that those kinds of photos inspire the manual stimulation that gets the blood flowing, Dr. Chivers found that just the sight of naked chicks in action worked on both straight men and women. This may explain the glut of girl-on-girl action from college co-eds on LastNightsParty.com to Angelina Jolie and Clint Eastwood’s wife.  Faux-lesbos are for real! [New York Times]
