No one's uterus gets quite as much attention as the one attached to Gisele Bundchen, which is why you've probably seen about a thousand tabloid stories about her being pregnant—or not being pregnant—over the past few months. Us Weekly is wading back into it this afternoon, reporting that "multiple sources" have confirmed that the supe and husband Tom Brady are expecting their first child together. Could this be the one? Let's hope so. This may be our best shot at ensuring that Kate & Jon finally get kicked off the covers of celeb tabloids sometime this summer. [Us Weekly]

It was pouring rain as they tried to hustle him quickly across the busy street to the safety of his trailer. Some of the teen girls were hysterical and Rob rushed across the road. As he did so, a taxi grazed him." Got that? It grazed him. So he's fine. Please pass that message along to your 16-year-old cousin, okay? Thanks. [RadarOnline/National Enquirer]

• This is a bizarre one: Two police chiefs in Ohio are now under investigation for allegedly breaking into the home of the surrogate mom hired by Sarah Jessica Parker and Matthew Broderick in an effort to dig up dirt on the woman, which they then planned to sell to the tabloids or use to blackmail the couple. [Us, E!, NYDN]

In news that will probably leave you speechless with surprise, Billy Joel and third wife Katie Lee Joel confirmed this afternoon they're splitting up. "After nearly five years of marriage, Billy and Katie have decided to separate," reps for the couple told the Daily News. "This decision is the result of much thought and consideration. Billy and Katie remain caring friends, with admiration and respect for each other." Naturally, the decision to part ways had nothing at all to do with the rumors that Lee's been dating designer Yigal Azrouël. They've been doing a very good job keeping that one under wraps, clearly. [NYDN]

New information has emerged on the child labor violations of "fledgling internet site" (ha) RadarOnline. We will cover this story with the same verve with which RadarOnline covers Octomom. Illegal, baby-endangering verve, that is!

• Here's a rather unlikely rumor but an amusing one all the same: Prince William is supposedly thinking of moving to America with his girlfriend, Kate Middleton, and the two have been spotted house-hunting in Malibu. Frankly, if they were going to move to America—and they're probably not—we see them as more of a New York couple. And NYC could use a prince roaming around, couldn't it? Let's all cross our fingers and hope for the best. [E!]
• Countess (and not-so-real housewife) LuAnn de Lesseps was spotted hanging out with young men and doing tequila shots at a club in the Hamptons last weekend. And the earth continues to rotate on its own axis, too. [P6]
• That was quick. Just a couple of weeks after Lindsay Lohan and Sam Ronson supposedly reunited, the couple appears to have split up again—and it's all Nicole Richie's fault, too. Or maybe they never got back together at all? Feel free to take your pick. [E!, People, AH]

The temporary replacement this week for recently laid-off Daily News gossip writer Sean Evans: Sarah Polonsky, who was once canned by Page Six for being a freebie-mongering "swag hag." And Jared Paul Stern is still available, hey! [CityFile]

Now this is some sort of karma: a report says that the state of California is going after RadarOnline for exploiting Octomom's kids, with their relentless Octomom videos. [UPDATED below]

The New York Daily News dismissed gossip writer Sean Evans last Friday. The paper has yet to name a replacement to head up the Gatecrasher column with Laura Schreffler, and from the looks of things, the recruitment process isn't going very smoothly. Filling in for the week is "swag hag" Sarah Polonsky, the former National Enquirer reporter who worked very briefly at Page Six in late 2006, but was fired for running afoul of the paper's ban on accepting freebies. (Most recently, she's headed up a website called Cellofame.com.) Guard your gift bags, publicists! Polonsky's email below.

Gossip is good for you. Or at least that was the conclusion of a study conducted at the University of Michigan, which aired up 160 women and had half of them proofread a botany paper and the other half dish about their personal lives. Twenty minutes later, the chatty Cathys had increased levels of progesterone, which is linked to "long term physical health and has anti-stress effects," whereas the women stuck talking about plants had decreased levels. So, basically, oversharing with strangers is good for your health. Debating Petunias, not so much. Of course, the more interesting study would examine the potenially salubrious effects of reading about other people's personal lives. Look for that study, sponsored by Us Weekly, E!, and Perez Hilton, in the coming months. [NYDN]

• Paris Hilton reportedly broke up with boyfriend Doug Reinhardt after she saw him partying with a "Texas beauty queen" named Kendhal Beal. The heiress responded by throwing a fit (and some fruit and ice in Beal's direction). But don't you worry about Paris. She's got her dependable sister by her side. And she's already moved on to someone new, namely soccer star Cristiano Ronaldo. [P6, People]

Warren St. John, the dreamy NYT reporter and author of incongruous 'Bama football book Rammer Jammer Yellow Hammer, has a heartwarming new book about refugee soccer players that is a smash hit. Why won't his own paper review it?

[Telegraph]
• On-again, off-again couple Leonardo DiCaprio and Bar Refaeli appear to be in "off" mode, according to People. But Us says Bar and Leo are still together and even have photos of the couple shopping yesterday to prove it. Say a little prayer and hope for the best, won't you? [People, Us]

Just imagine what's going to happen when the two actually face one another in court. [NYP]
• Lindsay Lohan and Sam Ronson appear to have reunited. Enjoy it while it lasts! If history is any guide, by this time next week, the couple will have had another messy brawl, LiLo will be melting down on Twitter, and Sam will be running off to another foreign country to get away from her. [Sun, People]
