Wow, look at those two!

Naomi Watts and Ewan McGregor stole the show in their outfits when they hit the red carpet for the premiere of their new film The Impossible at the Arclight Cinemas in Hollywood on Monday night.

The co-stars spared no expense for their gorgeous garb, with Ewan sporting a Balenciaga suit while Naomi was decked out in a Zac Posen dress, Jimmy Choo shoes, J/Hadley earrings, and a Jennifer Meyer ring and bracelet. They sure do know their style!

Naomi Watts has a gorgeous back, and the blonde beauty was proud to show it off at the UK premiere of The Impossible in London, England.

Watts strutted her sexy stuff on the red carpet in a black Tom Ford gown with voluminous draping sleeves.

She stars opposite Ewan McGregor in the flick which is set during the 2004 Thailand tsunami. The Impossible hits theaters next year.

Naomi Watts doesn't stick her boys on a school bus in the morning, she straps them into their bike seats and she and Liev Schreiber bike the boys to school!

Naomi's toted son Samuel Kai, 3, while Liev carried Alexander "Sasha" Pete, 4 through the streets of New York Friday. Adorable AND environmentally-friendly!

Forget Katsuya... the farmers market is the hippest place to be if you are a Hollywood couple with kids!

Naomi Watts and Liev Schreiber took their boys Sasha, 4, and Kai, 3, to the fresh food trading post in Santa Monica on Sunday, and we can't get over how much the little ones look exactly like their mom!

The Scream actor is well aware he hit the genetic lottery by having children with the J. Edgar actress too! He explains: "Typically would Naomi Watts be out of my grasp? Absolutely. What stupid pills she took seven years ago, I don't know. Oddly enough we have a lot in common. We grew up in similar ways. The other thing, it turns out that genetically we make exquisitely beautiful children."

The eco-friendly pair picked out some fruits and veggies before opting to bike home while towing their tots in a special kid carrier.

Now THAT is what we call Sunday Funday for toddlers!

Australian actress Naomi Watts will be playing Princess Diana in the upcoming biopic Caught In Flight.

The 43-year-old starlet, who happens to be BFFs with Nicole Kidman, said the following about playing the iconic role:

Happily unmarried couple Naomi Watts and Liev Schrieber have just plunked down $3.9 million on a 3 bed/2 bath co-op in NYC's trendy TriBeCa neighborhood, which sprawls across the entire 8th floor of the chic 1920's building.

The 4,315 square foot space includes key-lock elevator access, 14 foot ceilings, painted linoleum tile floors, two kitchens, and Hudson River views from the southwestern corner or the building.

The A-list couple also own a $4.3 million estate in the Hamptons on nearly three-quarters of an acre, with a swimming pool and separate guest cottage/pool house.

Halloween isn't over for Naomi Watts's darling little boys, Samuel and Sasha, who showed off spooky vampire teeth while enjoying a stroller ride with mom in NYC, on Tuesday.

We caught up with the Ring star all dressed up in a classic clown costume the day before, as she took her sons trick-or-treating in Manhattan with partner Liev Schreiber, who looked ultra spooky in a grim reaper costume.

It was recently announced Watts has signed on for the upcoming independent film, Sunlight Jr., costarring Matt Dillon.

The movie centers on a convenience store clerk Melissa (Watts) and her paraplegic boyfriend, Richie (Dillon) who are genuinely excited when they learn Melissa is pregnant, until she loses her job and things start to go horribly wrong.

Another Hollywood couple in a cheating scandal?

Reports surfaced this weekend that Liev Schreiber, 44, has cheated on longtime partner (and mother of his two sons), Naomi Watts, 43 -- and that it happened the same weekend Ashton Kutcher allegedly cheated on Demi Moore.

Was something in the water??

According to TheDirty.com, Liev had been filming Mental in Australia (where Naomi Watts is from.) In the film, a swimwear model named Phoebe Roberts (left, in Kulu Swimwear) served as body double for Liev's co-star, Toni Collette.

Schreiber and Roberts supposedly hooked up after the movie's wrap party on Sept. 24. The actor allegedly took Roberts back to his apartment.

Liev's rep has denied the allegations, saying, "This is a complete fabrication."

Schreiber and Watts have been a couple since 2005. We spotted them out together as recently as Sept. 27 in NYC -- only a few days after the alleged hook-up with Roberts. See the pic after the jump.
