It happens to the best of us!

Lady GaGa had a bit of a tumble while performing Teeth at her concert in Montreal.

Check it out around the :20 second mark above! But she got right back up like a pro!

GaGa ended up falling THREE times during that concert, the first show of her Monster Ball tour, as she was not yet fully accustomed to the precarious raked stage.

She later joked: "I'm like a drunk supermodel - and I LOVE it!" Ha

During the second show of the tour, Saturday night in Toronto, the Lady did not slip once.

These days Stephanie Pratt looks like a shell of her former self – but unlike most Tinseltowners who are quick say they popped the pounds with “diet & exercise,” the 23-year-old said being down in the dumps lead to a dramatic weight loss.

“It was 6 months of hating life! It was a great secret,” she told Tarts at a recent Hollywood bash when we asked how she lost so much weight. “I got backstabbed by half of my friends, and people stopped looking at me as a friend and more of a commodity and what they could get in the end. I am a very sensitive person to a fault, and I've never been mean to anyone and I kept on thinking, ‘What's wrong with me that makes these people treat me like this? What did I do to attract this?’”

And according to New York nutritionist and founder of SkinnyandtheCity.com Tanya Zuckerbrot, MS, RD Pratt’s now scary skinny body isn’t exactly healthy and she estimates the reality starlet has probably gone from 140 pounds to 112 in the last four-five months.

“For 5’7, her weight should be 135 plus or minus ten percent. She definitely looks underweight. The problem with losing so much weight so quickly is that your body is starved of key nutrients, and muscle wasting occurs. Muscle wasting is so detrimental to a person's health because the heart is a muscle, breaking down the muscles of your heart leads to heart attack, stroke and death,” Zuckerbrot (who does not treat Pratt explained. “Stephanie Pratt has the ability to be a positive role model to young girls. She should focus on representing realistic and achievable goals that girls can emulate. Currently Stephanie is underweight yet still leads a glamorous life, this sends a message to young girls that skin and bones equals fame and fortune. Stephanie needs to take control of her life and follow a healthy and consistent eating plan with at She needs to eat at least three regular meals and one snack. Stephanie needs to gain anywhere between 10-15 pounds.”

And even though Miss Pratt is certainly no angel, she wants to make sure you know that she’s nothing like her even more infamous brother, Spencer.

“The biggest misconception is that I’m like my brother, but I’m not. I’m much more sensitive, mellow and quiet,” Pratt explained.

Speaking of siblings, even Spencer’s sister-in-law Heidi Montag made a point of disassociating herself from the cheesy couple.

“People confuse me with my sister all the time,” Holly said. “People are like ‘Heidi! Why are you married to that douche bag?’ and I'm like, ‘That's my sister you're thinking of! I don't know really what to say!’” 

The "Hills" star reveals shocking reason behind her weightloss

So he says!

Alec Baldwin is co-hosting the upcoming Academy Awards and stars on NBC's 30 Rock, but he says when his contract with the sitcom expires in 2012 he's heading out of Tinseltown — potentially for good!

The actor revealed:

"I don't have any interest in acting anymore. Movies are part of my past. It's been 30 years. I'm not young, but I have time to do something else.

"It's a difficult thing to say, but I believe it: I consider my entire movie career a complete failure. I'll tell you why. The goal of moviemaking is to star in a film where your performance drives the film, and the film is either a soaring critical or commercial success, and I never had that."

Don't be too hard on yourself, Alec!

You're easily the most successful of all your brothers and you really are hilarious on 30 Rock!

Sunday was a busy travel day for everyone!

And that included Gwen Stefani, Gavin Rossdale, and their two adorable tots.

Gwen and Gavin were spotted arriving at LAX airport yesterday with little Zuma and Kingston ridding along in their strollers.

The siblings looked too cute!!!

And check out Kingston's hair!

Though for 3-years-old, Kingston looks pretty big. Too big for the stroller maybe?
