Happy 26th Birthday, Lady Gaga!

One of the most successful, buzzed-about singers in all of music turns 26 years young today. Happy birthday to Stefani Germanotta, a.k.a. Lady Gaga!

The only question is how the New York native will celebrate.

From urging fans to donate money to victims of the Japanese earthquake to using her star power to promote gay rights and denounce bullying, she's never been one to rest on her laurels - even during as self-imposed media blackout.

This year promises to be quieter for Gaga following 2011's release of her smash hit sophomore album Born This Way, but don't expect her to fade away.

Not by a long shot.

Love Lady Gaga or hate her, there's no debate over the impact this artist has had on the industry, and her immense popularity with fans is unquestioned.

Naked or clothed, with or without makeup, dressed like a slab of meat or a rumored hermaphrodite, we love us some Gaga. And we're clearly not alone.

Here's wishing her a happy 26th birthday, and hoping for much more entertainment in the years go come. Here are some favorite recent Lady Gaga pics:

Rihanna and Ashton Kutcher: Rumored One-Night Stand Alert!

On Tuesday around midnight, according to TMZ, Rihanna pulled up at Ashton Kutcher’s house. A blurry pic of Rih in her SUV (with her security detail) was posted online as the celebrity gossip site claimed she stayed at his bachelor pad until 4 a.m.

We can imagine that, whatever they were up to (and we're guessing it wasn't any sort of business collaboration) Ashton wouldn't be thrilled about the story.

But what's the harm, really? Did he threaten them to take the photos and/or the whole story down? And why would they comply if it was so obviously true?

TMZ of all sites is usually extremely accurate and willing to stand by its reporting. Shady, maybe, but not wrong, nor on the wrong side of the law. Weird.

In any case, that's what allegedly happened before the story got killed. And we can see it happening more easily than we can Johnny Depp and Ashley Olsen.

Tia Carrere Fired on Celebrity Apprentice

Following a task that didn't go as planned, Tia Carrere ended up being the latest casualty of Donald Trump's unforgiving boardroom cuts on Celebrity Apprentice.

On Sunday's episode, both teams were challenged to create a viral video for an O-Cedar mop. Obviously. The men, led by Lou Ferrigno, took a comical route.

The women, however, went with a double entendre "What's your number?" campaign.

While not overtly sexual, each woman, under the direction of Lisa Lampanelli and guidance of project manager Carrere, revealed how many mops they'd owned in their lives.

The men's idea mopped the floor with them and raised $50,000 for charity, leaving the ladies - Carrere, Lampanelli and Aubrey O'Day - fighting for survival.

When push came to shove, Carrere stepped up ... and fell on her own sword.

"Unfortunately I know as project manager, my head is on the chopping block," she told Trump, believing that someone else would go down with her.
