Amanda Seyfried will do anything for her pooch.

The actress braved New York City's frigid temperatures to take her dog Finn out for a walk. Amanda tried to keep warm in a pink beanie, knitted scarf, raincoat and Ugg boots.

Amanda, who's often joined by boyfriend Justin Long on these Big Apple dog walks, was solo. Unlike last year, she's not wrapped up in the awards season shuffle. Her two major films, Lovelace and The Big Wedding, bombed at the box office. Next year will hopefully bring more commercial success and critical acclaim.

The Mean Girls star is currently filming Noah Baumbach's While We're Young with Ben Stiller and Naomi Watts. She just signed on to star in Will Ferrell and Adam McKay's He’s F---ing Perfect.

It's Britney, bi**h!

Britney Spears put the sin back in Sin City during the debut of her two-year Las Vegas residency on Friday. The premiere performance drew a sold-out, star-studded crowd that included Miley Cyrus, Katy Perry, Selena Gomez, Kellen Lutz, and Adam Lambert.

Brit-Brit kicked of her new show, “Britney: Piece of Me,” at Planet Hollywood Resort & Casino by performing the classics (“Baby One More Time,” “Oops I Did It Again,” “Toxic,” “Womanizer,” “Slave 4 U,” etc.) before singing new tracks from her latest album, Britney Jean.

The pop star frantically traded one racy getup for the next (costume designer Marco Marco has truly outdone himself) during the frenetic, 90-minute concert. She even performed a bondage routine, complete with spanking audience member Mario Lopez with a studded harness. The Cirque du Soleil-esque routine also included acrobatics and airborne wire acts.

Britney will take the stage again on Tuesday for a special New Year's Eve performance. If yesterday's act is any indication of the future 100 ones to come, Britney's got herself a hit.

There was no white Christmas for the Lopezes, but fun in the sun.

Mario Lopez, his wife Courtney and their family spent the holidays in Puerto Vallarta, where they celebrated their baby boy Dominic's first Christmas and the couple's first wedding anniversary. The Extra host and his fam stayed at the Garza Blanca Preserve Resort & Spa along with Mario's sister, her husband and their four kids.





The doting dad showered his 3-month-old son with affection and spent plenty of quality time with his 3-year-old daughter, Gia. When they weren't frolicking on the beach or playing in the pool, the foursome explored the city by hiking in the jungle. The parents even found time during the week for paddle boarding and kayaking.

With 2014 just around the corner, it's out with the old and in with the new for Eva Longoria.

Things seem to be getting serious between the actress and her new beau Jose Antonio Baston. The couple was spotted on not one, but two dates on Friday: They first grabbed lunch then dined at Il Piccolino in West Hollywood.

After parting ways with Ernesto Arguello in August, the former Desperate Housewives star has been cozying up to Baston, the president of Latin American TV network Televisa, in recent months. The pair made their first public appearance at the Museo Jumex opening in Mexico City in November then attended Art Basel in Miami earlier this month. Now that's one cultured duo.

The two were most likely celebrating Eva's new contract with Televisa, which commits her to three telenovelas, the first of which will be Cuna de Lobos opposite William Levy. It apparently pays to date the boss.

The former soap opera star stunned in a hot pink dress that fit her snugly up front with a belted waist yet fell loose in the back like a cape. She completed the look with black pumps and a matching black studded clutch.

They certainly look like they are dating!

Khloe Kardarshian and Matt Kemp further sparked romance rumors when they were caught going to the gym together on Friday afternoon.

While they may have left the gym separately -- we think it's pretty clear these two were sweating it out at the gym together.

For the workout, Khloe was outfitted in a black, long-sleeved shirt, cropped leggings and bright orange Nike shoes. The Dodgers player wore a gray and black track suit and carried his gym gear in a camo backpack.

Rumors first started swirling about the potential couple when Kemp Instagramed a photo of the Kardashian family's Christmas tree. And then X17online had the first photos of the two together -- following each other to the gym, of course. Their relationship seems to have a strong root in physical fitness - hey, at least this is a healthy couple!

T-minus 5 hours and counting!

Britney Spears Tweeted a sneak peek at her Las Vegas show, which opens TONIGHT in Las Vegas, along with these words ...

Gwen Stefani can do no wrong! Taking sons Zuma and Kingston to church on Christmas Eve, the pregnant mother of two was on-point in a super mod, black-and-white ensemble. And we love that the boys wore matching outfits, which perfectly complemented their mom's chic look.

The family that matches together -- stays together!

Gwen wore signature platinum locks in a sideswept 'do added a pop of color with bold cherry red lips. Kingston, 7, and Zuma, 5, were outfitted in matching in black-and-white striped bow ties, matching black-and-white striped pants and white short-sleeved dress shirts.

We are kind of obsessed with these three!

Nice stems, LeAnn!

Country crooner LeAnn Rimes wore quite the eye-catching dress when she showed off some major leg on Tuesday. The blonde had all eyes on her as she headed to do some last-minute shopping at the Grove on Christmas Eve.

The singer-turned-reality star rocked a body conscious grey tank dress for her Christmas Eve outing. Eddie Cibrian's lady love was looking lean -- her blonde tresses windblown as she headed into the outdoor mall.

Earlier, as she left home to head to West Hollywood, the "Blue" singer tweeted, “Wow the amount of paparazzi waiting outside of the gates of our neighborhood is insane. This shall be an eventful last minute shopping trip.”

We wonder if she got anything good!
