Katy Perry had a pretty swanky penthouse in the Tribeca neighborhood of New York City, but I guess the memories it held were a bit too much for her to take, especially since it's the first love nest she owned with husband Russell Brand. (Ouch.)

She just sold the pad for $2.75 million, which sounds like a pretty decent price considering its size. The apartment had plenty of space for the newly single star at 1,500 square feet, and also came complete with a limestone kitchen, cherry wood staircase, 2 bedrooms, and 2 bathrooms. It also had an outdoor terrace with beautiful views, but the sights inside the place probably weren't too appealing to Katy anymore.

Well, looks like somebody changes her mind like a girl changes clothes ... and her name is Katy Perry! Yes, the ex-Mrs. Russell Brand is reportedly "moving on" -- and wouldn't you know it, there's proof!

Because Perry and her new dude, Florence and the Machine guitarist Robert Ackroyd, were all about the PDA at Coachella (though between Alicia Silverstone's kid and Rihanna snorting coke off some guy's head, it's a miracle anybody noticed).

So let's put this news into perspective, shall we? A newly single gal in her 20's made out with a hot guy at a music festival ...

Katy Perry won't have to worry about finding a new place to live after her split from Russell Brand, because he flat out gave her the rights to their spectacular $6.5 million L.A. mansion, which is located on the famous Sunset Strip.

Wow. That's pretty generous of him, isn't it? Considering that he's also not getting one cent of her $44 million fortune, it seems kind of strange that he wouldn't put up a fight for the house. He must really want to make sure he severs all ties to Katy once and for all. (Either that, or he's really nuts.)

Forbes' list of the most overexposed celebrities is out, so I thought I'd expose these overexposed celebrities a little more by exposing how overexposed they are. You can probably guess who tops the list -- 65 percent of people polled said that Kim Kardashian was the most overexposed star to date. Although it would seem that her entire family would place in the top five, Lindsay Lohan came in second, Snooki came in third, the Octomom came in fourth, and Paris Hilton came in fifth. Kourtney and Khloe were eighth and ninth, respectively.

The list sounds about right to me, hard to argue with the top three celebs. But one question: what the hell is Paris Hilton doing on this list? Last I heard, she was whispering slow raps about drunk texting. She's trying her best to be overexposed, but sorry, she's kind of not on my radar anymore. But you know who is?

Hey! Katy Perry wants y'all to know whassup fo' realz! Cuz girl wasn't tryin' ta diss on Beyonce, okay? #gangstatweetz

Translation: Katy Perry took to Twitter today to address that snide little comment she made about Beyonce and Shakira's old duet, "Beautiful Liar" (namely that she doesn't want her eventual duet with Rihanna to suck as badly). And it totally wasn't an insult, she insists.

On Twitter, Katy Perry explained that she was simply trying to say ... well, I'm not really sure what she was trying to say.

Katy Perry is a firecracker. Between her wild outfits, her wigs, and her song, er, "Firework," the 27-year-old pop star is unpredictable. She speaks, and sings, her mind, which is great for us, sometimes not that great for her. After a radio interview with the BBC, it's been declared that she and Beyonce are now feuding because of Katy's harsh words about Beyonce's duet with Shakira. Uh. Oh.

Katy explained to the station that she and her good friend Rihanna are planning on putting out a duet, but that they're not in any hurry. Katy wants it to be right. Katy wants it to be "iconic." Katy wants to make sure it's nothing like Beyonce's song, "Beautiful Liars." Diss.

Katy Perry is just a friend, people!Okay, I'll admit my first reaction to the rumors of Robert Pattinson "texting and calling" Katy Perry "every day" wasn't pretty. (Imagine lots of muttering and cursing about "that blue-haired bimbo" and "who does she think she is" and "she's no Kristen Stewart, I can tell you that much.") But of course once I calmed down a bit and reviewed the "facts" (meaning the gossip nobody has confirmed or will confirm), I realized the very idea of RPattz ever cheating on KStew is ree-diculous. Absurd!

Pattinson is merely doing everything he can to be there for his good friend during this, her time of crisis. Checking in on his pal. Sweet guy that he is, would we really expect anything less?

I bet those RPattz/Katy Perry texts went a little something like this ...

Katy weirded out by the ironic timing of her single, "Part of Me"When Katy Perry debuted her new single, "Part of Me," during the Grammys, on that intense, fiery set wearing a gold spacesuit-ish ensemble and rocking short deep blue krimped hair, we all assumed the performance was an "in-your-face" to estranged hubby Russell Brand. Hellooo ... the lyrics seem to make it so obvious: "You can keep the diamond ring/It don't mean nothing anyway. In fact, you can keep everything -- except for me."

But Katy told MTV News, "Some people that I work with were like 'You should just say you wrote it a couple of weeks ago.' I'm like 'I'm not a d---, I'm going to tell the truth.'" And the truth is that the song is two years old ... and thus, not at all about Russell.
