Is Christina Aguilera Battling Alcohol, Weight Gain Problems?

The latest issues of Star magazine reports that pop icon Christina Aguilera has been battling alcohol issues. The magazine plastered a picture of a disheveled Aguilera on the company's most recent magazine cover.

Star claims that Aguilera has been drinking all night and sleeping all day. In addition to the accusing Aguilera of being an alcoholic, Star reports that Aguilera has gained 65 pounds.

Sources close to Aguilera say, [Aguilera is] out of control, and hated by The Voice co-stars and crew. She is getting wasted a lot and just embarrassing herself.

The tabloid also says that Aguilera left her son, Max, on his 4th birthday in order to get drunk.

In the magazine, a source explains:

Christina's lost her confidence since she split from Jordan. She gets terribly sad, and that's when all the awful memories come flooding back and she ends up numbing herself with booze and food. Everyone is worried sick. She needs to get help before something even more serious happens.

Not so fast says Rumor Fix, an entertainment blog.

This is all false. notice the photos [in the magazine] are over one year old. Christina hasn't shot The Voice since last year so there are no 'problems' as they state, says the Rumor Fix source. And she is busy working and recording and doing very well. There are also photos from Max's birthday the day before, of, and after where she and Max are at Legoland and at the hotel. Nobody is drunk by ANY means

So what do you think?

Has Aguilera seemed off-kilter on The Voice?
