Back when Kelly Osbourne was struggling with her weight, the Fashion Police c0-host claims Christina Aguilera called her out for being fat. Now, the tables have turned, and it’s the other way around! Kelly is looking great – and Christina not-so-much.

On E!’s Fashion Police Friday, the 26-year-old slammed Christina Aguilera for her weight. “She called me fat for years,” Osbourne said. “I was never that fat.”But Ozzy’s daughter wasn’t the only cohost to attack Aguilera’s figure. “Lady Marmalade got into the peanut butter again,” Joan Rivers sniped.

“I’m looking at this and thinking, ‘Well, she’s put on weight. This just isn’t flattering,’” George Kotsiopoulos said. “But this is just a crappy outfit, regardless. No matter what shape your body is in, it’s just bad.”

Kotsiopoulos pointed out Aguilera was “still probably a size 2/4,” but Osbourne was quick to disagree.

“Trust me,” she said. “I’m a 2/4. That is not a 2/4.”

What goes around comes around. Here are pictures of Christina Aguilera and her boyfriend Matthew at the pumpkin patch with her son, Max.

Here are pictures of Snooki Christina Aguilera performing at Saturday’s Michael Jackson Tribute Concert in Cardiff, Wales.

Apparently her voice was flawless as she performed covers of Smile and Dirty Diana, but we can’t say the same for her ensemble. Her blonde wig was a hot mess!

Taking the stage in a a skin-tight bodysuit and tights, the 30-year-old singer followed the celebrity trend of shunning pants that’s been popular for the last few years.

With clownish makeup and bleach blonde extensions looking ratty and tangled, the singer’s appearance shocked the audience as she performed Charlie Chaplin’s “Smile.”

For her second set the singer changed into a more flattering outfit, but still didn’t look quite like the songstress fans are used to seeing.

Christina Aguilera’s 3-year-old son with ex-husband Jordan Bratman was recently photographed sporting a black eye.

An insider close to the singer, 30, explains that little Max fell while chasing squirrels at the park.

“Any reports stating she isn’t a good mom are incorrect,” the source tells Us Weekly. “The reports are actually disgusting. Christina is an amazing mom. Max is a happy playful and active boy who has a loving and safe home.”

Chasing squirrels? I have two sons – and they are as rambunctious as they come. But chasing squirrels? A broken nose from that!?

Christina Aguilera is firing back at rumors she’s somehow responsible for a giant bruise on her son’s face — telling friends little Max simply had himself a little fall at the park … chasing squirrels.

The photo was taken yesterday afternoon at LAX — with rumors circulating that Christina’s “erratic behavior and alleged booze-filled outings” somehow contributed to Max’s accident.

But sources tells us, that’s total nonsense — 3-year-old Max was out with his nanny last week, chasing around squirrels … and the kid tripped over a rock and bruised his face.

According to our sources, Max was taken to the doctor immediately and everything was fine. No broken nose, no stitches. Just your average boyhood bruise.

As one source put it, “Christina is a great mom … Max is her #1 priority.”

You buying the squirrel story? It’s so weird, right!?

Several websites are reporting that Max was spotted with a bruise under his eyes.  That is quite a bit more than a simple bruise – that kiddo’s nose is broken! The bruise goes under both eyes, and it’s obvious his nose is swollen. Poor kid! Wonder what happened?

Christina Aguilera and Matt Rutler arrived at Los Angeles Airport this afternoon with Max.

Christina is set to perform at an upcoming tribute concert for Michael Jackson, but reportedly many fans of MJ are lobbying for it’s cancellation.

The group “criticized the timing of the show, which coincides with the trial of Dr. Conrad Murray for involuntary manslaughter in the death of Jackson, and expressed confusion over the event’s charitable donations and high ticket prices,” Rolling Stone reports.

I think no one would argue the fact that it’s been a rough year for Christina Aguilera. The 30-year-old singer is on the cover of W Magazine this month, and inside she opens up about how rough this year has been for her, the childhood pain she still carries, and how she keeps a level head through all of it.

“I felt caged by my childhood. And unsafe: Bad things happened in my home; there was violence,” she confessed to the magazine. “‘The Sound of Music’ looked like a form of release. I would open my bedroom window to sing out like Maria. In my own way, I’d be in those hills.”

It was her Grammy-winning voice that brought her trouble on the biggest stage of the world last February, when she flubbed the lyrics to the National Anthem at the Super Bowl.

“Everything on the field at the Super Bowl was vividly bright, and I was having a moment,” Aguilera said about that embarrassing mistake. “I got lost in the emotion of being there and I messed up the lyrics to the song.”

She took it well, though; while she knew that it’d get major play in the media, she tried to laugh it off.

“I went to dinner after the Super Bowl with Matt and I laughed about how I’d made myself into a Trivial ­Pursuit question: ‘In 2011 what female singer flubbed the lyrics to the national anthem?’” she remembered.

The Matt, of course, is Matthew Rutler, her new boyfriend. She met him on the set of her film debut, the ill-fated “Burlesque,” and soon after, announced her divorce from husband of five years, Jordan Brattman. To hear her tell the story, the split was mutual — and mutually sinful.

“At one time or another,” ­Aguilera she said, alluding to affairs, “we were both not angels. It got to a point where our life at home was reminding me of my own childhood. I will not have my son grow up in a tension-­filled home. I knew there would be a negative reaction in the press to my divorce, but I am not ­going to live my life because of something someone might say. That goes against everything I sing on my records. I have to be myself.”

And speaking of “Burlesque,” in which she, for the first time, wasn’t playing herself, she doesn’t regret making the movie, even if it failed. Because she didn’t.

“I was sad, but I’m still glad that I did the movie,” she said about the film. “During production, I was going through a lot of self-discovery. As a quote-unquote pop star, you have your entourage with you at all times. When you enter and leave a place, backstage, even at home—you always have your team. On the movie set, I didn’t have anyone around me. And it felt good. When I first met my husband, I needed that ­helping hand to take the reins and look after me. After the movie, I grew out of being that little girl: I became more of an adult.”
