Entertainment Tonight

Cheese steaks and the Liberty Bell aren't the only famous things to come out of Philadelphia – add Justin Guarini to the list! Last year's ""American Idol"" runner-up jets back to his hometown for the opening of ""From Justin to Kelly"" (opposite Kelly Clarkson) and ET's on site with the story! After that: Jim Carrey is a tough act to follow. Can anyone really top his performance in ""Dumb & Dumber""? An unknown actor goes for glory in ""Dumb and Dumberer: When Harry Met Lloyd.""

ET's packin' star power on tonight's half-hour! We'll kick things off at the L.A. premiere of Harrison Ford's latest pic, ""Hollywood Homicide."" Be there as Ford and co-star Josh Hartnett scorch the red carpet -- will Harrison bring Calista? Who'll be on Josh's arm? Don't miss ET's up-close coverage. Also: Leann Rimes has your First Look at her cool new music video. It's the title track to Reese Witherspoon's ""Legally Blonde 2""...catch it only on tonight's telecast!

Some outfits cause jaws to drop and flashbulbs to pop. Others are so hip, they kick off trends. Yet one thing's for sure: the MTV Movie Awards always feature the ""Best & Worst"" dressed celebs in the biz! On this edition, ET rolls tape on the good, the bad and the barely-there looks that scorched the red carpet! Then: ""Bruce Almighty"" and ""The Matrix Reloaded"" will be facing some stiff competition at the box office, so before you go out, tune in ET's weekend movie rundown.

Most actors would be intimidated working with industry pros like Adam Arkin, Joely Fisher and Elliott Gould. Not ""Baby Bob""! He's the 6-month-old talking tyke who's returning to CBS tomorrow night -- and ET has the inside dish! After that, keep it here for a no-holds-barred interview with Priscilla Presley. In this tantalizing conversation, Presley shares what she really thought of daughter Lisa Marie's marriage to pop icon Michael Jackson in an ET exclusive!

Every summer, a ""sleeper"" roars out of nowhere to wow the moviegoing crowds. Two years ago, that flick was ""The Fast and the Furious,"" which racked up over $145 million. Now, ET feeds your need for speed as we take you to the premiere of the red-hot sequel, ""2 Fast 2 Furious."" With Paul Walker back in the driver's seat and Tyrese and Ludacris joining the mix, get set for an adrenaline-rushing ride through the streets of Miami!

It's probably the only awards ceremony where celebrity guests are upstaged by the likes of Donna Karan and Ralph Lauren. Last night, the Council of Fashion Designers of America recognized the nation's style leaders. Tonight, ET unveils the big winners and the big stars in attendance! Plus: where do celebs like Bruce Willis hang when they hit Sin City? From Taboo to Ghost Bar, ET slips you the coolest clubs in Vegas!

With categories like ""Best Kiss"" and ""Best Fight,"" you can be sure the MTV Movie Awards are a lot looser than the Oscars! So, did Eminem beat ""SpiderMan"" (Tobey Maguire)? Did Halle Berry whip Reese Witherspoon? And which lip-lockin' pair puckered all the way to the top? ET's on the scene and backstage! Later: Harrison Ford gets talks about his romance with Calista Flockhart in a revealing chat with Mary Hart.

From the yachts to the casinos to the couples, nobody captures the French Riviera scene like the upcoming HV-1 special, ""Red Hot Red Carpet: ET Goes to Cannes."" Our own Maria Menounos takes you inside the world's most famous film fest for an exclusive look at the people, the parties and the players! We'll slip you into A-list events with Nicole Kidman, Keanu Reeves, and Penelope Cruz, and crash Naomi Campbell's ""topless"" Saint-Tropez birthday bash!

With Drew Barrymore, Cameron Diaz and Lucy Liu in the cast, get set to gorge on ""eye candy"" when ""Charlie's Angels: Full Throttle"" opens next month. Don't wanna wait? ET delivers an eye-popping preview you'll see nowhere else but on ET's telecast! Also: Arnold Schwarzenegger joins forces with ET to run down the list of Hollywood's top action heroes and villains. Will ""The Terminator"" make the cut?

So, where are you going on your summer vacation? ET reveals where the stars go in a jet-setting report that uncovers the posh hangouts of the rich and famous! Then: he's the highest-paid actor on television, but can Ray Romano conquer the big screen, too?
