After spending a few days in Paris, Jennifer Aniston and Justin Theroux jetted off to Rome to continue their romantic holiday abroad!

The happy pair took in the sights as they flashed their matching "Jen" and "Justin" rings, but while we have to admit the Friends star looked smokin' hot in that skintight grey dress, she got a bit of flack for wearing a dress that was "too short" to The Vatican. But when you've got a flawless body like Jen, sin not to flaunt it.

Justin recently revealed he "couldn't be happier" with his girlfriend of one-year, and after looking at these pix, it's not hard to see why!

Looking bright and beautiful in a rainbow-colored dress, all eyes were on a Paris Hilton as she made her way to AV nightclub in Hollywood, on Saturday afternoon.

The Heiress partied the night away with her girlfriends, but ended the night on a more low-key note, Tweeting: "At home in bed watching Project X. So hilarious, love funny party movies!"

Loves it!

She may be due any day now, but Kourtney Kardashian never slows down!

The mom-to-be and beau Scott Disick treated their son 2-year-old son Mason to an outing at the LA Zoo, on Saturday afternoon, looking maternity-chic in oversized shades and a blue maxi-dress, as she pushed her son's stroller around the park while Scott chatted away on his cell phone.

Early this week Kourt sparked rumors she had already given birth to her baby girl, after Tweeting: "Chick-fil-A and a water birth. No big deal." But she later cleared up the miss understanding, adding: "Witnessed a water birth last night with @KhloeKardashian. What an experience! All I can say is WOW!"

Gavin Rossdale has been on the road for several weeks touring with his band Bush, so it's no surprise Gwen Stefani busted out her sexiest outfit to reunite with her hubby at his LA concert!

The blonde bombshell showed off her lovely legs in skintight black pants, sky-high stilettos and a hot pink jacket as she made her way in to the venue to see Gavin rock out with his bandmates, Tweeting Friday night: "On our way to staples for @bushofficial @GavinRossdale bush show."

Gwen will soon be busy with her own band, No Doubt, when the group releases their upcoming album after a decade-long hiatus. The band recently shared on their offical website: “Hope you are sitting down, because we've got some really big news to share with you! While adding the finishing touches to our new album we realized it was time to name it … so we did, and the name is … (drum roll please) … Push and Shove!!!”

Push and Shove is No Doubt's sixth studio album, and it's set to be released September 25 -- we can't wait!

In celebration of Project Runway's 10th anniversary, Heidi Klum joined costars Tim Gunn, Michael Kors and Nina Garcia for the show's season premiere in Times Square, on Friday night.

The Victoria's Secret Angel looked stunning in a green cocktail dress as she kicked off the newest season by announcing: “'I can't believe that it is Project Runway's 10th anniversary already! What an amazing milestone. I'm incredibly proud of the show and everything we've accomplished.”

Klum added, “[The show] has been a great platform for many talented designers. Fans come up to me every day saying how much they love the show – that means so much.”

The 10th season of Project Runway premieres July 19 on Lifetime.

Talk about a hot ride!

Looking casual-cool in a striped shirt and jeans, Hayden Christensen headed to the gas station solo to fill up his $100K Audi R8 in Los Feliz, on Friday afternoon.

The 31-year-old Canadian actor is currently in pre-production for the thriller, The Diplomat which centers on a junior diplomat who is thrown into a violent conspiracy when his daughter witnesses the murder of the US Ambassador to Ireland.

We want to know when the Star Wars star will finally tie the knot with fiance Rachel Bilson!

After her health scare at the Ritz-Carlton Marina del Rey, near the Liz & Dick movie set Friday morning, Lindsay Lohan may have had a religious awakening!

We spotted Lohan paying a visit to the Scientology Centre in Hollywood on Friday night, and it seems her assistant Gavin Doyle may have something to do with her new-found interested in the celeb-friendly religion.

A source tells X17 exclusively:

"Lindsay is obsessing over the Scientology Centre where she's filming. Now she wants to move in. Gavin, apparently, sparked a huge interest in her and they want to join together."

A 911 call was placed Friday morning after Lindsay was reportedly found unresponsive in her hotel room, due to exhaustion from working insane hours for the upcoming Elizabeth Taylor biopic, but the actress assured fans she was doing much better Saturday morning, Tweeting:

"Note to self.. After working 85 hours in 4 days, and being up all night shooting, be very aware that you might pass out from exhaustion & 7 paramedics MIGHT show up @ your door... Hopefully they're cute. Otherwise it would be a real let down."

Linds then added "Back on set."

Lohan's mom Dina told X17 exclusively after her daughter's scare: "Lindsay's ok. She worked until 6:15am and wrapped, then went home to sleep. She's working so hard and just wants it to be perfect."

Maybe Scientology would help Linds balance life and work and keep her on the straight and narrow!

Jennifer Garner is a pro at planning little girl's birthday parties, so she was more than happy to oblige for pal Matt Damon's eldest daughter Isabella's celebration in Brentwood, on Friday afternoon.

The Oscar winner's daughter was born June 11 in Miami, but the family decided to throw her 6th birthday bash this weekend, and it looks like it's going to be a fancy party.

Happy birthday Isabella!
