Like many celebrities, Christina Aguilera has definitely experienced her fair share of ups and downs in the spotlight.

(Remember her nasty divorce, the bizarre party crashing, and that time she screwed up the National Anthem?)

However, the 31-year-old coach for The Voice has been completely open – and completely unapologetic – about them all.

Recently, the pop sensation opened up to Lucky about another kind of up-and-down element of her life – her weight – and offers fans a bit of advice about not only being comfortable with themselves, but learning to use and be proud of what they’ve got:

Actually, the challenge I’ve always had is being too thin, so I love that now I have a booty, and obviously I love showing my cleavage. Hey, if you can work it and you can own it, that confidence is going to shine through.

How true is that?

Even though he once said he’d never write one, Neil Young has a memoir coming out next week…

…and he’s quit drugs.

The 66-year-old singer-songwriter recently sat down with David Carr of The New York Times to talk about his new autobiography, Waging Heavy Peace, and his year-long sobriety.

(Of course, that’s just the condensed version; there’s a little more to the story – like the time he was arrested on drug charges with Eric Clapton and Stephen Stills, and the time he partied with Charles Manson).

Today (September 16, 2012) at 2 p.m. EDT, Daniel Radcliffe (Harry Potter, The Woman in Black) will host a live chat discussing suicide prevention for The Trevor Project National Suicide Prevention Month Campaign, Talk to Me.

The campaign’s goal is to raise awareness about suicide prevention, and Radcliffe will talk about issues and questions submitted online as well as by members of The Trevor Project’s Youth Advisory Board. Shira Lazar (What’s Trending With Shira Lazar) will moderate the live chat.

Of the campaign, Radcliffe, 2011 Trevor Hero Award honoree, says:

Suicide is absolutely tragic, and it’s also completely preventable, which is why it is so important to learn how to help during The Trevor Project’s National Suicide Prevention Month. The Trevor Project is full of amazing volunteers who work every day to save lives on the phone and online, but the Talk to Me campaign is about how each one of us can help save a life, too. I am really proud to be a part of this extraordinary initiative with The Trevor Project.

The chat will broadcast live via The Trevor Project’s YouTube and Google+ pages as well as on www.trevortalktome.org.

(HINT: If you get over to Talk to Me now, you might still have time to send in a question for Daniel!)

Today, September 10, 2012, is World Suicide Prevention Day.

According to the World Health Organization (WHO) and the International Association for Suicide Prevention (IASP), one million people die by suicide each year.

It only makes sense that there’ll be numerous suicide prevention and awareness events throughout the world today, and because we have a celebrity theme here at Celebrity Psychings, I want to share tonight’s Grassroots Suicide Prevention event with you.

Starting at 8 p.m. BST (that’s British Summer Time; find out what time it is now and a converter tool at timeanddate.com), the Grassroots Suicide Prevention organization will begin live-streaming an hour of its Protective Factors and Instilling Hope event.

(Hmm… Didn’t we just do a weekend post on Alanis Morissette?)

Alanis Morissette recently appeared on “Chelsea Lately” and talked with host Chelsea Handler about her postpartum depression.

The 38-year-old songstress admitted to Handler that she waited too long to ask for help (a year and four months!) but, when Handler suggested that’s why she was eager to write an album, Morissette claimed “Havoc and Bright Lights” was unaffected by her depression.

Mostly.

There’s a song called ‘Numb,’ where I write about recovery.

Last week, Nicole “Snooki” Polizzi gave birth to Lorenzo Dominic LaValle (her first little meatball with Jionni LaValle), and although she claims she’s “slowly getting her swag back,” the 24-year-old Jersey Shore reality star was quick to admit to her fans that things aren’t immediately peachy after having a baby:

Post birth isn’t so comfy and glamorous. But my son is FABULOUS.
