Christina Aguilera "Can Laugh" About Messy Life

Christina Aguilera is the first one to admit that she's had a rocky few months.

The singer -- who, within one month's time, flubbed the National Anthem during the Super Bowl, collapsed onstage at the Grammy Awards and was jailed for public intoxication -- says she's ready to turn things around.

"In light of the past year, there have been obvious setbacks," she told Us Magazine on Monday. "I've gone through a really hard divorce, and anyone who has gone through a divorce will speak about how hard the journey is from start to finish."

"It's a life-uprooting time and there have been hiccups along the way that unfortunately the whole world gets to witness and judge," she added.

The 30-year-old pop star -- and mom to 3-year-old Max, her son with ex Jordan Bratman -- said her recent slip-ups have been a blessing in disguise.

"I can laugh about my own hiccups and my own experiences in life because I'm getting through it," Aguilera said. "But I get to share these experiences with these people and I get to say not every performance day is going to be a great day."

"Sometimes you could be having the worst day of your life and you have to get up on that stage and you have to give to your fans in a way that they would never know the difference," she continued. "You have to lose yourself in that moment and you have to be so involved. Take yourself out of your own headspace or use whatever you're going through and put it into the passion of your song."

Lady Gaga Kicks Adam Lambert Out Of Party

Adam Lambert made quite the impression at Lady Gaga's surprise twenty-fifth birthday party Sunday night, and not in a good way.

The American Idol alum, 29, wasn't even invited to the bash at L.A.'s La Cita Mexican restaurant, but attended as a guest of the Scissor Sisters, who have been opening for the "Born this Way" singer on tour, Perez Hilton told the Morning Dish radio program Thursday.

"Adam showed up beyond drunk," said the gossip blogger. "Super sloppy embarrassingly drunk!"

Lambert began some intense fist-pumping and kept beating on the walls until he'd actually punched a hole in the building's low ceiling, Hilton said.

And another eyewitness tells Us Magazine, "Adam acted like an animal. He kept jumping up on the tables and chairs and screaming. When they brought the cake out he tried to smear it in Gaga's face and put a doll from the cake in her mouth!"

Then the "Whataya Want from Me" singer tried to serenade the birthday girl, "like he was auditioning for Idol again!" Hilton said.

Eventually Gaga asked her security to kick him out, added the witness.

A rep for Lambert had no comment on the incident, but a few days later, Lambert acknowledged his bad behavior on his Twitter page.

"My hand still hurts. LoL," he wrote Wednesday. "Was trying for celebratory gesture 4 gaga's B- piñata style...instead my fist is all bruised and la cita has a hole in the ceiling. #sloppy."

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.")
