Christina Passes Out in Jeremy Renner's Bed

Finding Christina Aguilera between his sheets was hardly a dream come true for Jeremy Renner. Popping up uninvited at Renner's 40th birthday bash on January 8, the singer, 30, got "wasted" then lay down in the star's bed, a source tells the new Us Weekly, out Wednesday.

A week later, Renner went on a rant about the incident at In Style's Golden Globe party after seeing Aguilera at the fete.

"Someone comes and tells me she's in my room," he told pals at the Jan. 16 affair. "I run up and open the door and I'm like, 'Um, hi. What are you doing?' She just starts slurring. Her boyfriend [Matthew Rutler] was rubbing her back. Who comes to someone's birthday party that they don't know and gets in their bed?! My parents were there!"

Adds another source, "Christina was a mess at that party. She acted like a fool. Her boyfriend was shushing her and telling her to go to sleep."

(Renner's rep says that Aguilera "was enjoying herself, but she wasn't in his bed.")

Christina Aguilera's Is Not Engaged To New Man

Christina Aguilera's new boyfriend put a ring on it, but don't get the wrong idea.

Matt Rutler "gave [a ring] to her for her birthday," a source tells PEOPLE. "It's not an engagement ring and they're not engaged. It was a surprise gift from him."

Although the lovebirds aren't necessarily saying "I do" anytime soon, they are getting more serious. Rutler's mom has had the honor of meeting Aguilera. And Rutler was by Aguilera's side at her New Year's Eve bash, which was attended by her own mother, brother and sister.

Aguilera recently introduced Rutler to her son Max when she brought him to the Peterson Automotive Museum.

"Christina took Max on the fun outing so he could bond with Matt," a source says. "Max was initially a bit shy, but later warmed up to Matt. It seems very important to Christina that Max got along with Matt."

The source also says Rutler has been spending the majority of his time staying at Aguilera's Beverly Hills home, while the singer's ex, Jordan Bratman, is now living in a rental home nearby.

Christina Aguilera: New Chapter In The New Year

Christina Aguilera, who just turned 30, is ready for a fresh start – and what better way to celebrate than with a big bash for her family and friends?

The singer and Burlesque star threw a party at her Beverly Hills home on New Year's Eve, with 175 guests, including her new man Matt Rutler and celeb pals and newlyweds Nicole Richie and Joel Madden.

Aguilera – who toasted the New Year with a custom bottle of Moët champagne with her name engraved on it – wowed the crowd in a silver sequin Herve Leger dress and jeweled Christian Louboutin heels. "She was so excited!" a guest tells PEOPLE. "She was all smiles all night and really relaxed. She's had a tough year, but she looked genuinely happy."

Indeed, the singer recently confided her anticipation of the event in an interview with PEOPLE. "This party is all about counting down to the new chapter of my life," she said. "I'll be surrounded by friends and family who care and love me to death."

With the party and the kick off of 2011, she's closing the book on a difficult year in which she filed for divorce from her husband Jordan Bratman.

"It's really a time for me to look forward to the next chapter in my life," Aguilera added. "I couldn't think of a better way to bring in the New Year [than with a party]."

The event was also about good old-fashioned fun, and featured a Tarot card reader, a photo booth, three bars, a dance floor and deejay and a sushi bar. After midnight, mini egg McMuffins were served as the first breakfast of 2011.

As for hitting the big 3-0, Aguilera says she has no worries on growing older.

"Everything is exciting right now," she says. "I'm an actress and I'm a single mom. I'm entering my thirties. I'm looking at this as an exciting new chapter in my life."

If the eve of the New Year is anything to go by, she's looking at a good year ahead, according to one guest. "At midnight, she got up on stage and thanked everyone for coming. She told everyone how excited she was about the new year, and how normally New Year's Eve parties are usually a disappointment, but this year she wanted all her friends to have a really fun night. And it was! It was a great party."

Christina Aguilera & BF On Horse-Drawn Sleigh

Christina Aguilera celebrated her 30th birthday with her love Matthew Rutler in high, yuletide style on Saturday Dec. 18.

Sipping wine and wearing mouse-ear style earmuffs, Aguilera cuddled with Rutler in a white horse-drawn carriage; the duo stayed at Hotel le Lana, a luxury ski resort in Courchevel, France.

Set assistant Rutler befriended Aguilera while she shot Burlesque; they reconnected after her September split from husband Jordan Bratman. She and Bratman, 33 were married for five years and have a son, Max.

Rutler has been "really for her and is helping her through this difficult time," a pal recently told Us Magazine.

How does the star feel about turning 30? "It's better than turning 20, I'll tell you that," she told Ellen DeGeneres last month. "You're more comfortable in your own skin as a woman. You have a better idea of what you want and how to get it. At this time in my life, it's a huge turning point, it's a transitional stage and I'm ready. I'm ready."

Christina Aguilera's 30th Birthday in French Alps

Christina Aguilera celebrated her 30th birthday in the French Alps this weekend with a mix of pleasure and a little business.

Topping off a weeklong jaunt across Europe, the singer and boyfriend Matt Rutler flew on Saturday from Berlin to the posh French ski resort of Courchevel.

There, they immediately headed out in a two-horse-drawn sleigh, with glasses of wine in hand – white for her, red for him – as they took in the chalet sights and views on a ride around the village, an eyewitness tells PEOPLE.

Afterward, they returned to the luxury hotel Le Lana before Christina headed over to Les Caves disco, where she had a special singing engagement – performing a late-night set as the surprise guest at Ukranian industrialist Victor Pinchuk's 50th birthday party, which also included a special performance of Cirque du Soleil.

It's been a whirlwind week for the lovebirds, who hit a London nightspot, a Paris strip club and Berlin's elegant Christmas Market along the way.

Christina Aguilera & BF Share Christmas Spirit

Christina Aguilera and her new guy Matt Rutler went seasonally traditional in Germany on Thursday, strolling through Berlin's elegant Christmas Market – all hot on the heels of their European travels, first to a London nightspot, then to a Paris strip club.

In the German city, with the premiere of her movie Burlesque about to take place with 1,000 fans already gathered outside the cinema, the couple meandered through the market stands and booths, even stopping to purchase some sugared almonds. Staving off the subfreezing cold, they also shared some hot mulled wine.

The came show time, and the couple quickly returned to their hotel to change for the red carpet.
