Jason Sudeikis and girlfriend Olivia Wilde are engaged!

According to a source for Us Magazine, Sudeikis proposed just after the holidays, and the insider added, "He finally found the one that made him want to commit. They've both been through it before and this has just felt right from the get go. Everyone is happy for them."

The couple were first linked in December of 2011, and both have been married before. Wilde was married to filmmaker and prince Tao Ruspoli for 8 years (the two split in 2011) and Sudiekis was previously married to actress and 30 Rock writer Kay Cannon from 2004 to 2010.

Congrats!

Ever since The Hills ended, it seems like we catch up with Lauren Conrad about 4 times a year! Not like we miss her that much, but it's always interesting to see what the reality star turned fashion designer is up to!

Lauren was snapped grabbing a bite at The Griddle in West Hollywood with a pal, and surprisingly, she didn't pull her usual duck and cover when she spotted photogs.

While the 26-year-old starlet has found some success with her novel series, it seems like she's always plugging her clothing collection these days. Hey, now that she's not making $120k per episode, she's gotta hustle!

Now that's hot!

Paris Hilton and beau River Viiperi jetted from Los Angeles to Mexico today, and not only did they travel with several pals, but the heiress got to meet her man's sister Luna for the first time.

After hopping off the plane, Paris immediately slipped into a bikini and struck a sexy pose. "The weather is beautiful," she tweeted. "Loves it! Can't wait to jump in the pool!"

Can't wait to see more photos from her vacay!

She may be a doting mother of three by day, but on Sunday night she's going to be all glammed up at the Golden Globe Awards!

And after that it's the SAGs, the DGAs, the BAFTAs and even though hubby Ben Affleck got snubbed by the Academy for a Best Director nomination, we have a feeling Jen will be by his side at the Oscars next month, as Argo is nominated for Best Picture.

Jen has been hitting the gym hard, and it also seems like someone has stepped up their game with styling Jen's daily wardrobe (and Ben's, for that matter), so we can't wait to see her red carpet looks over the next few weeks!

She sure likes 'em young!

Demi Moore, 50, is dating Harry Morton, 31, who is famous for owning the Viper Room and Pink Taco, but even more well known for his tumultuous relationship with troubled starlet Lindsay Lohan.

According to E! News, the couple have been dating "for a few months" after meeting him through mutual friends. "They have been trying to keep it a secret," an insider says. "It's not a serious thing ... but it may develop into something. They have a lot of fun together and have been meeting in secret places in New York and Los Angeles ... They are just getting to know one another. [Moore is] in a really good place at the moment and is hopeful about the future."

The duo went on a dinner date at South Beverly Grill in Beverly Hills on Wednesday, and according to eyewitnesses, they arrived around 8pm and were "flirtatious, laughing and appearing to have a great time," during the two hours they spend there. Around 10pm the couple drove back to Moore's place and Harry went inside, where he presumably spend the night.

Lance Armstrong is reportedly planing to come clean about his doping scandal to Oprah Winfrey, according to sources for USA Today.

Armstrong, 41, who was banned from cycling and stripped of his seven Tour de France titles last year, is scheduled to tape an interview with Winfrey on Monday at his home in Austin, Texas. The segment will air Thursday on the Oprah Winfrey Network, and Armstrong will "admit to doping throughout his career but probably will not get into great detail about specific cases and events," the insider reveals.

Armstrong has denied using performance enhancing drugs for years, but back in October the U.S. Anti-Doping Agency released substantial evidence that showed otherwise. In addition to losing his titles and being banned from the sport, Armstrong was dropped by his sponsors dropped him and forced to step down from his cancer charity Livestrong.

Armstrong does run the risk of being sued or held liable by individuals who believe he defrauded them by lying about doping, and though it's not likely, he could face criminal prosecution as well, since he testified under oath in 2005 that he never used drugs. While his admission will not lift the ban, if can provide substantial assistance to doping officials USA Today reports that it could be considered in reducing his ban.

Natalie Portman and her darling little boy Aleph met up with some friends at the park in Beverly Hills on Friday, and she may be on mommy duty at the moment, but it looks like 2013 is the year she's getting her career back!

The Oscar winner will star opposite Christian Bale and Cate Blanchett in the new Terrence Malick flick, Knight of Cups, the sequel to Thor comes out this year, and that's not all! This spring Natalie is set to begin production on Jane Got a Gun and she's rumored to be starring in In the Garden of Beasts opposite Tom Hanks, which is about "a mild-mannered Chicago professor who becomes America's first ambassador to Hitler's Germany just before the Nazis began to assert an iron grip across Europe," according to IMDb. She's going to be quite busy!

Maybe her ballet dancer hubby Benjamin Millepied plans on being a stay at home dad?

Jason Trawick has resigned as Britney Spears's co-conservator.

On Friday Los Angeles Superior Court Judge Reva Goetz stated, "The court accepts the resignation [of Trawick]," adding that Britney's father Jamie Spears "will remain as the sole conservator of her person."

Jamie has held control over Britney and her finances since she suffered a mental breakdown in February of 2008, and Trawick was added as a co-conservator in April 2012, approximately four months after the couple got engaged. Trawick did not handle her estate, but he was in charge of her person, which gave him the authority to make decisions about her general well-being, such as food, clothing, travel and medical care.

On Friday, the couple also confirmed that they had ended their relationship of nearly three years. "Jason and I have decided to call off our engagement. I'll always adore him and we will remain great friends," Spears said in a statement to People. Trawick added, "As this chapter ends for us a new one begins. I love and cherish her and her boys and we will be close forever."
