The Stanley Cup—aka Canada's Holy Grail, from which, legend has it, one sip of Labatt Blue renders the drinker immortal—took some time off from its current damnation home in Detroit to take in some local sunshine and glamour. Starting in Manhattan Beach at the home of former San Jose Shark Brad Stuart, the cup then bounced into its rental (a convertible Sebring) and hightailed it down to Chris Chelios's place in Malibu. It stopped for breakfast at Coogie's Beach Café, where a cup-struck Rob Reiner bashfully approached it and requested a photograph. But it was once it arrived at Bally's gym owner John Wildman's annual Fourth of July party that it really started getting caught up in the Hollywood fast lane, rubbing handles with the likes of Detroit's own Kid Rock, David Spade, Cuba Gooding Jr., Ray Liotta, and Jeremy Piven. The Stanley Cup Journal blog reports:

With a flank of beef spitting on the rotisserie, [Hollywood Records exec group] Steal Thunder took the stage. Jeremy Piven got up and beat the heat by keeping the beat on the bongos. Then, Kid Rock decided to rock the stage. [...]

Which Hottest Woman In The 'Maxim' Universe Totally Blew Off Jeremy Piven At The Guys Choice Awards?

When not proposing Entourage cameos to some of the world's greatest hell-to-the-divas, Jeremy Piven can often be found sidling up to one of our city's endlessly replenishable starlets with a patented ice-breaker ("So, have you been to India?"). The desired result is frequently achieved, and within minutes the two are zipping off in a hydrogen-powered Bentley to his place for a better look at his dhoti collection. Sometimes, however, Piven shoots a little too high, and his hottie-air balloon comes crashing down to the ground. Take, for example, a recent run-in with America's #1 fanboy-bait-object:

Jeremy Piven Takes It Upon Himself To Cast New 'Entourage' Star After One Too Many Fruitinis In First Class

Jeremy Piven is important, he will have you know. He can pick up girls in a hooptie. He can cut Stephen Dorff in bathroom lines. He can tell Billy Bush to fuck off on the red carpet and his own mother to fuck off over brunch. And, as Janet Charlton reports today, he can also cast wildly eccentric and ill-suited stars in cameos on Entourage based solely on fun chatter he has with them on airplanes. As the piece claims:

“On a recent weekend, Jeremy rode the Planet Hollywood private jet from Las Vegas to Los Angeles and...started chatting about Entourage. [Piven] suggested that it would be fun to have [his seatmate] make an appearance...Jeremy was overheard calling a producer and telling him as soon as the plane touched down in LA.”

So which diva extraordinaire tickled Piven’s pickle so well she earned herself a much-needed spot on the HBO hit? Details after the jump.

In Honor Of Ryan Seacrest's 'Momma's Boys,' We Salute Hollywood's Greatest Oedipal Wrecks

In light of the news that Ruler of the Universe Ryan Seacrest will soon be hosting a show on NBC called Momma’s Boys, we’re both delighted that the highlighted wunderkind has decided to ignore all the inevitable backlash, and disappointed that the show will be using mere mortals as contestants. Of all the male celebrities out there, Ryan is undoubtedly one of the most clear-cut examples of how we imagine our worst nightmare of a "Mother May I?" type to be, but he’s certainly not alone. Below, we nominate a few of our own submissions to the casting call printed in Backstage this week for “candidates who should be ready to be humiliated,” in celebrity form of course:

Jeremy Piven's Passion For Life Misinterpreted As Violent Temper

Here's how we picture Jeremy Piven spent his weekend: Seated in a darkened theater, two attractive brunettes on either side, staring up at Robert Downey Jr. engaged in a delightful bit of business involving not-yet-perfected booster-boot technology, and thinking to himself, "I can do that." That said, here's your latest Piv update, courtesy of Rush & Molloy:

Jeremy Piven strikes again. The "Entourage" star and cad-about-town had a "knock-down, all-out screaming match" with a brunette by the pool area of Diddy's after-party for his Hollywood Star Walk of Fame ceremony.

Jeremy Piven Typecasting Epidemic Spreads To Broadway

Perhaps needing a break from the fast-talking, potty-mouthed, morally askew Hollywood wheeler-dealer he plays on Entourage, Jeremy Piven is taking to the Broadway stage to play one of the fast-talking, potty-mouthed, morally askew Hollywood wheeler-dealers of David Mamet's Speed-the-Plow:

Jeremy Piven makes his [Broadway] debut this fall in a revival of David Mamet's biz satire "Speed-the-Plow." [...]

Many Psilocybin Surprises In Store For The Boys Of 'Entourage'

What would happen if the douchey Entourage cast all took a bunch of 'shrooms and headed out to the desert to "find themselves?" According to EW.com, we'll soon learn. As creator Doug Ellin puts it, "The boys trek to Mexico and Joshua Tree National Park...they'll eat some psychedelic mushrooms...It's one of my favorite episodes. It's their Into the Wild trip." But as any fan of psychedelics knows, the concept of putting four man-children out in the middle of nowhere with nothing but widened minds to entertain themselves can only lead to (further) homoeroticsm and cannibalism. Our hallucinogenic fever-vision after the jump:

When Trolling For Sexually Adventurous Models, Jeremy Piven Believes It's Best To Hedge One's Bets

One of the most difficult decisions facing today's television watching youth is whether or not to absolutely loathe or laughably love beach yogi Jeremy Piven. And that head-scratcher has been made that much more difficult this morning when confronted with news that the (already taken) actor allegedly asked two models for their numbers at the same party on Monday night in New York, only to discover later that the two Amazonians were besties. Gross, correct? But! He slightly redeems himself by providing Page Six with this stellar quote:

"It was my hope that in texting both ladies, I would make it onto Page Six, so everybody wins."
