Uninvited Christina Aguilera a Drunken Mess at Jeremy Renner’s Birthday Party?

[HMG Celebrity News] – We mentioned how Christina Aguilera seemed to recently pick a fight with ‘Burlesque’ co-star, Julianne Hough. The 30-year old singer was attending a Golden Globe afterparty thrown by her agents ‘CAA’ at Soho House, a private club on Sunset Boulevard in West Hollywood. No-one’s quite sure what set Christina off but when Julianne entered the room Christina immediately got in her face.

Another recent story has emerged that may give some insight as to what is going on with Aguilera.  Jeremy Renner spotted Aguilera at the In Style’s Golden Globe party and reportedly told his own bizarre encounter with her.  Aguilera supposedly showed up uninvited at Renner’s 40th birthday bash on January 8, where she proceeded to get “wasted” then lay down in the star’s bed, a source tells Us Weekly.

“Someone comes and tells me she’s in my room,” he supposedly told friends 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 agent mostly refuted the story, saying that Aguilera “was enjoying herself at the party, but she wasn’t in his bed.”

Still I won’t be surprised if Christina Aguilera quietly enters rehab soon.
