After spending time in London and Madrid, Rihanna's latest stop is Milan, Italy. We spotted the R&B superstar dining at Da Giacomo restaurant with her bodyguard last night, but where was boyfriend Matt Kemp? Didn't the two just have dinner on Sunday evening after MTV's European Music Awards?

Nicole Richie is already in fine form, but a few extra workouts before her December wedding certainly can't hurt!

We snapped the bride to be leaving the gym in Studio City yesterday afternoon, and with less than a month to go until she walks down the aisle with Joel Madden, you can bet the hot mama is busting her booty on the treadmill. We definitely can't wait to see her wedding dress -- think it'll be one of her own designs?

Conan O'Brien truly delivered tonight on the premiere of his TBS show Conan, and from our favorite bear to a snarky (but somewhat tame) opening monologue, we couldn't be more thrilled about his return to television.

When he started off the show, O'Brien joked, "Welcome to my second annual first show ... People ask me why I named the show Conan. I did it so I’d be harder to replace. This is an exciting night. I’m glad to be on cable. The truth is, I’ve dreamed of being a talk show host on basic cable ever since I was 46."

Conan continued, “A lot’s happened in the news since I went off the air — and I was hoping I could cover it all in one joke. But then I realized that’s like trying to keep an Icelandic volcano from wearing Lady Gaga’s meat dress while a trapped Chilean miner cleans up the BP oil spill…Brett Favre’s p*nis.” Immediately after this we got a peek at the infamous masturbating bear, and over the course of the rest of the show Conan chatted with guests Seth Rogen, Glee's Lea Michelle and he even jammed with musician Jack White. Take that, Jay Leno!

Can't wait to see what kind of numbers the red-headed comedian brought in tonight. Did you guys love it as much as we did?

Brad Pitt is staying extremely close to ladylove Angelina Jolie's side while she shoots her directorial film debut in Budapest, Hungary.

Our photographer on the scene tells X17online that the 46-year-old father of six has been "extremely hands on" while on set: "He was walking around with two cameras, two tripods -- he was all over it. I'm pretty sure he's handling all the still photography of the set."

Reports have surfaced that there may be a bit of a power struggle between the couple on set but our snappers say everyone involved in the production knows who's the boss; "Angelina is really comfortable letting Brad help. She feels confident in her role as director and the crew seem to understand who they report too -- there's no confusion."

And loves the short red bob on Amanda Seyfried! Sure, it's just a wig, but still. Hot look for the 24-year-old starlet!

Seyfried (who plays Sylvia Weis in the sci-fi flick) joined Justin Timberlake on the set of Now in Los Angeles earlier this afternoon and both donned some futuristic-looking outfits. Too bad Amanda's covering up that funky dress though! Andrew Niccol's highly anticipated thriller - he wrote Gattaca and The Truman Show - comes out in 2011.

Seriously! The svelte blonde looks better than ever these days. I know everyone talks about how lucky she is to be dating True Blood hunk Alexander Skarsgard, but he's the lucky one! Kate Bosworth looked ab fab while leaving James' Beach Restaurant in Venice on Sunday...

The actress is currently filming rom-com BFF & Baby about how the lives of two best friends changes when one of them has a baby. Hmm, kinda sounds like a Kate Hudson vehicle, right?

Maria Shriver and her kids regularly attend their weekend yoga class in Brentwood, but this is one of the few times we've seen Arnold Schwarzenegger go with 'em!

The California governor finishes his term this January when Jerry Brown will step in to replace him.

Meanwhile, Patrick looks as cute as ever - the celebrity son even flashed us the peace sign as he drove off!

Ali Larter -- whose belly looks ready to pop -- was eating for two yesterday at Ammo in Hollywood.

Accompanied by her hot hubby Hayes MacArthur, the pair (who will soon become a trio) met friends at the trendy eaterie.

Rumor has it that Ali's due date is Christmas day, but we bet she looks like she'll be delivering her baby boy a little closer to Thanksgiving!
