After a brief honeymoon with cupcake and various delicious treats, Grey's Anatomy star Katherine Heigl switched back to the Hollywood power diet of cigarettes and Diet Coke. Heigl has cited the change in diet for the overall improvement in her disposition. Heigl said, "I was always so bitchy and crazy when I was ingesting sugar all the time. Now that I'm back to the natural elements, the basics, I don't know. I feel so energized and not dreading everything. I'm starting to not mind Joshua's bitching and even sometimes, allowing him to call himself, Josh. "

We've been poking fun at Katherine Heigl for months now, and with good reason: she just can't stop saying the darndest things about her emasculated husband Joshua Kelley, she is completely lacking gaydar ... frankly, this list could go on for hours. But after hearing the news that Heigl is pushing for an escape from the ratings-challenged Grey's Anatomy following a fiscally successful contract renegotiation later made public, we're inching towards Team Heigl for the first time. As a source tells MSNBC:

Sorry boys, It appears as if Scarlett Johansson really is taken. As we noted yesterday, 2006's Sexiest Woman Alive got engaged to equally easy-on-the-eyes boyfriend Ryan Reynolds, and judging from ScarJo's behavior last night at the Costume Institute Gala, the soon-to-be-bride appears incapable of hiding her joy. All smiles as she walked the carpet, Johansson even did the paparazzi a favor by flashing her new rock, and her choice to wear an off-white demure dress helped us paint some mental images of her upcoming walk down the aisle. But how does her ring compare to infamous engagement rings of the past (J. Lo's sad pink diamond monster mid-Bennifer trainwreck) and rings recently sported by newly engaged stars like Mariah Carey and Ashlee Simpson? We compare and contrast after the jump.

OK, OK, Hollywood Reporter — we get it. The trade paper today took 1,600 words, three pie charts, two line graphs, and a half-dozen adorable floating-head info boxes to confirm the long-suspected word on the street that — are you ready? — the star system is dying. Jim Carrey can't open! Brad Pitt's last film did $4 million! Julia Roberts hasn't broken $70 million since 2001! Shriek!

Katherine Heigl once again had to remind every one of the set of her new film, The Ugly Truth, the rules regarding her Ugg boots. Heigl had it written into her contract that she's allowed to wear her Uggs in scenes where her feet aren't visible, and even added a clause that gives her the authority to fire any crew members who snicker, giggle or engage in any other form of laugh-based communication either to her face or behind her back. Heigl told the crew that if they can't adhere to these rules then they could try to get somebody else who'll open the #1. That reminder sure shut them all up.

America's former sweetheart Julia Roberts talked to any one would listen about "the good old days" when she was at the top of the gossip heap. Roberts complained that the stars of today no longer have to go through multiple marriages like they used to in order to get on the cover of People. She went on to explain that she practically pioneered the strategy of dating someone way, way, WAY way out of their league (like she did with Lyle Lovett) in an effort to grab the headlines. Roberts then muttered something under her breath about reality television when the paparazzi quickly exited the scene after getting a hot tip about someone from The Hills shopping at a nearby Sephora.

If you observe Judd Apatow's pervy rom-com assembly line with even casual frequency, you probably don't need a Wikipedia entry to remind you how accusations of sexism and misogyny have plagued the writer-producer-director over the years. At least we hope you don't, because an eagle-eyed Defamer reader points out this morning how a loyal defender / relative / Universal publicist has spent the better part of the last week expunging the dirty little non-secret from the Wiki record. From Katherine Heigl to Mike White, follow the jump for a few of the latest line edits.

The embattled 27 Dresses star has been looking to change her public persona from a chain-smoking emasculator (who occasionally gorges on the sweets) to the bright and smiley persona she so frequently portrays on television and in the movies. Heigl's first step is to start practicing Tai Chi on a daily basis, which friends told her might help her kick her smoking habit. Also, as she politely put it, practicing this ancient art should help "keep Joshua interested. He is a rock star, after all."

This photograph of Katherine Heigl was taken after she received word that once again she was the punch line of a joke on gossip site. She then proceeded to eat all the sweets that the craft services table had to offer, including one quickly devoured Hostess cupcake. Reportedly, Heigl phoned her friend and asked why she would be the victim of constant attacks. "I'm a good person. I'm not perfect, but I'm a pretty decent person," Heigl was overheard saying. "Just ask Joshua."

As we've come to learn over the past few months, Katherine Heigl wears the pants in her relationship with crooner Josh "Call Me Joshua" Kelley. She's made it clear that when it comes to baby-making, attracting gay men and winning Hollywood over, Heigl will have us know that she pretty much outperforms her hubby in every way. And just to prove her point that much further, Josh's beloved Katie will soon appear on the big screen wearing a very tight pair of tighty whities. And putting our strained relationship with "the next Julia Roberts" aside, we must say she's about to give Tom Cruise a run for his money.

Katherine Heigl struck a gangster lean as she lit up another cigarette on the set of her new movie. Despite numerous tearful outbursts from her emasculated rocker hubby Joshua Kelley and the support of her Grey's co star TR Knight, she has not been able to kick the filthy habit. As Heigl reached for the nearest pack of American Spirits, she explained to an extra that if TR couldn't get her to quit, then what's the point?

What did we learn about our favorite celebrities this week? Glad you asked!
· Katie Holmes: She got sheared (next up, tannis root?) and, when it comes to meals, she's half a person.

· David Letterman: Doesn't mind giving audiences his sloppy seconds.
· Harvey Levin: Was an idealistic young rabble rouser and a foul-mouthed C-Word dropper.

Not only does Katherine Heigl lack the sensitivity gene when it comes to her marital bliss, but she's also missing a hefty dose of gaydar. Before her Grey's Anatomy co-star T.R. Knight was sweetly outed by since-fired Isaiah Washington, Katie apparently had a big ol' schoolgirl crush on him during the first season. And in standard Heigl fashion, she simply couldn't comprehend why T.R. wasn't showering her with affection after weeks of batting her lashes and sending out ostentatious signals. As The Sun quotes Katie:
