Hollywood Dirt: Miley’s Supposed Engagement Ring + Simon Cowell’s Home Invasion & More

ARE MILEY CYRUS AND LIAM HEMSWORTH ENGAGED??? - WE REPORT, YOU DECIDE: Is MILEY CYRUS trying to tell us something, or is it some kind of marketing ploy? We Report, You Decide! First she Tweeted a picture of her hand -- supposedly to show off her nail foundations. “I am soooo obsessed with jennahipp nail foundations! It looks so chic and classic!” Cyrus wrote.

But the photo of her left hand clearly showed her wearing what looks like a massive rock on her engagement finger. If Miley didn't want us to see the ring, she could have taken a picture of her RIGHT hand instead, dontchathink? Unless the tweet was a bit of marketing genius. If people hit up her Twitter account to see her ring, they’ll inevitably see her hand and whatever a nail foundation is, you follow?

But then on Saturday, she showed up at a charity event with LIAM HEMSWORTH, and she was still wearing it. Neither Miley, Liam, nor their peeps have commented on the pic or the ring.

KIM KARDASHIAN TO PRESS CHARGES IN FLOUR BOMB INCIDENT AFTERALL: KIM KARDASHIAN intends to press charges against the woman who hit her with a flour-bomb on the red carpet afterall. Kim originally told police to let it go, but upon further review, she's changed her mind. She says, quote, "I don't want someone to think they can really get away with that. So we are going to handle that." That's right, no one should ever sprinkle useless products on someone else, unless it's an exclusive Kardashian Kollection perfume or body spray!!!

Kim adds, quote, "Now that [I've] had some time to digest it, I think, 'What if that was some other substance? What if that person had a dangerous weapon?' It's scary."  You know what else scares Kim? That a Greek collapse could lead to a slip in Italian and Irish securities, eventually destabilizing Europe and eroding economical gains domestically. Kidding! 73-day long marriages do.

Meanwhile ... People for the Ethical Treatment of Animals wants you to know they were not behind it. But while a rep for PETA said they had nothing to do with the attack, they aren’t exactly condemning it. “It was not [us],” a rep told TMZ. "[But maybe] whoever threw that flour may reach her when our polite appeals [have] not."

CELEBRITIES IN TROUBLE - ROB KARDASHIAN DETAINED BY POLICE: ROB KARDASHIAN was handcuffed and put in the back of a police car after he pretended to chase down a paparazzo. It happened late Saturday night in Miami. Rob was hanging with some friends when he saw the photographer taking pictures of him from across the street. So as a “joke”, he started running at the guy.

The photog failed to see the joke aspect of Rob running towards him, so he took off, screaming for help, and ran into a nearby smoke shop. Rob kept after him, but supposedly only to tell him that he was just kidding. Unfortunately for Rob, police witnessed the whole thing and also failed to catch on that it was all a “joke”, so they followed Rob into the shop and cuffed him.

In the end, though, the Kardashian's little brother was let go after police spoke with both him and the photographer and straightened things out.

CRAZY LADY BREAKS INTO SIMON COWELL'S HOUSE WHILE SIMON'S WATCHING TV: Check out what happened to SIMON COWELL over the weekend as he was watching TV at his house in London Saturday night…

Simon had reportedly just finished watching HIMSELF on "Britain's Got Talent" when he heard a noise coming from one of the upstairs bathrooms. When he stupidly bravely went to check it out, he found a 29-year-old woman standing there with a brick in her hand!!

The woman is said to have gotten in the house through a downstairs window, and had apparently been wandering around the place for a while before Simon found her. At one point, she was also believed to have been lying in his bed. Members of Simon’s staff eventually detained the woman, and police were called. The woman was arrested for suspicion of burglary, although there are no reports of anything taken from the premises.

DID MEGAN FOX SPEND TENS OF THOUSANDS TO TRANSFORM HER FACE?: "In Touch Weekly" is claiming that MEGAN FOX has spent upwards of $60,000 on cosmetic procedures "to transform herself into what she [believes] to be beautiful." The magazine consulted an "expert" to look at a bunch of pictures of Megan and speculate on what procedures she's had. Here’s what he thinks: an eye lift, botox, work on her nose, cheek implants or fillers, plumped up lips, a mole removed, and either laser skin resurfacing, chemical peels or both.

“In Touch” also quotes a source who claims that being dumped from the "Transformers" movie is what led to Megan getting work done on her. "She was terrified [it] was bad for her career,” says the source. "So she decided to transform herself into what she believed to be beautiful."
