Why did Xtina decide to dump him again?!

Jordan Bratman took his and Christina Aguilera's son Max to the park in Malibu for a playdate on Sunday, and we can't help but think that the "Dirty" singer made a bad decision ditching such a hands-on dad and overall nice guy! The toddler seems to spend more time with dad than he does with mom, but considering she is busy judging The Voice we can't be too hard on her!

Maybe she's also been too occupied babysitting her boy toy Matthew Rutler?! We caught the loved up duo grabbing dinner and drinks with friends at Giorgio Baldi in Santa Monica on Saturday... must be nice being on on the Grammy winner's payroll!

Christina Aguilera and her boyfriend Matt Rutler are lovebirds who love a good after party!

The twosome celebrated The Voice finale at Avalon in Hollywood. Xtina, still rockin' her false lashes from the taping, also sported some short shorts and fishnets.

We couldn't help but notice that she was wearing one of her favorite tees with a topless Heidi Klum on the front. The singer wore this shirt more than two years ago while taping her cameo for HBO's Entourage.

Great to see that Xtina is a recessionista ... recycling old clothes!

The Wanted's guitarist Tom Parker is definitely not a fan of Christina Aguilera.

In a recent interview with New York's radio station NOW FM, Parker recalled meeting Aguilera on the set of The Voice after the band's performance.

Tom tells NOW FM:

"She's a total b*tch. She might not be a b*tch in real life, but to us, she was a total bitch. She just sat there and didn't speak to us. Wouldn't even look at us."

His band mate, Siva Kaneswaran added, "She was quite rude. Who does that?"

Yikes! Perhaps Xtina just wasn't having a good night.

Christina Aguilera, and her rapidly shrinking body, hit up Craig's restaurant in LA for a late night bite.

Boyfriend Matthew Rutler was right by her side ... helping his ladylove make it to the car safely.

After dinner, the lovebirds headed to the Sunset Marquis to keep the party going. We have to admit, these two have lasted longer than we predicted.

You go, girl!

Divalicious!

Covering up her curves in a short black dress and tights, the sexiest thing about Christina Aguilera's outfit was her Louboutins, but she still rocked her trademark red lips and struck some cute poses for the camera at an LA-area Starbucks, on Thursday afternoon.

Meanwhile Jennifer Lopez looked fierce in a skintight coral dress and some pretty bling, as she worked it for her own photo shoot at the CBS studios just a few blocks away.

If you had to choose; which Grammy winner looked the hottest?

Christina Aguilera definitely has The Voice ... and now the body, too!

While stepping out with her sexy beau Matt Rutler for a bite at Little Door in LA, Xtina proudly showed off her shrinking waistline.

Great to see the "Ain't No Other Man" songstress wearing form-fitting clothes again and sporting minimal makeup. We can't deny, she's looking fabulous!

Flaunting her newly slimmed down figure in a black skull tube dress with black tights and sky high heels, Christina Aguilera made sure to stand out in her electric blue cardigan and white fedora hat as she hit up celeb fashion Mecca, Fred Segal, on Monday.

The Burlesque star spent some quality time browsing the racks at the trendy West Hollywood boutique, before getting ready to appear on Monday's episode of The Voice, which is the first live show of the season!

It sounds like Aguilera has already picked her favorite singers thus far, Tweeting last night, "Ashley is a STAR!!!!!!!! Team X!!!!!!!!!" She added, "@LindseyPavao where can I buy your album NOW!! I could listen to your voice ALL DAY!"

We can't wait to see who wins!

Christina Aguilera's massive Beverly Hills mansion has been on the market for $13.5 million for about a year now, but she's decided to post even more photos of the property in an attempt to unload it.

The 6 bedroom, 9 bathroom pad is boldly decorated in pink and red, and it boasts a gym, a gift-wrapping room, a game room, a home theater, a guest house with a recording studio and there's even a salon! Outside there is a pool with a water slide and a grotto spa, and we're not sure how much of the furniture would stay with the house, but there's plenty of it!

Aguilera paid $11.5 million for the house in 2008, so perhaps she might want to think about lowering the price or redecorating? Just a thought!
