Christina Aguilera can sing, but no one was listening to her golden tones last night. And not in a good way. 

The “Beautiful” singer performed “Moves Like Jagger” with fellow judge on “The Voice,” Adam Levine but all eyes were on her atrocious ensemble which-- yet again-- surfaced speculation of a possible pregnancy.

Wearing a tight, unflattering bandage dress, Aguilera appeared to have a potato sack in her mid-area. Her plunging neckline didn’t help, as her breasts threatened to pull a Janet Jackson wardrobe malfunction. 

This is strike two for Aguilera in the wardrobe department.

Earlier this month, a sloppy-looking Aguilera took the stage at Michael Jackson’s tribute concert at the Millennium Stadium in Cardiff, Wales.

The star’s performance was on point, but her outfit was off, as her blonde hair was in disarray and her voluptuous figure was barely contained in her tight fishnet stocking and corset.

Aguilera, 30, later sported a navy blue ensemble with Military detailing favored by the King of Pop, which was more flattering to her physique.

Rumors are swirling that the “Beautiful” singer just can’t get a grip in keeping her weight under control and it’s driving her nuts, In Touch Magazine reported.

“Christina hates her thunder thighs,” a source and alleged close friend told the magazine.

The source added that despite having a personal trainer, nutritionist and hypnotist the weight is just not coming off.

Her camp has debunked rumors that Aguilera is expecting.

Puerto Rican singer Bruno Mars, who introduced Aguilera and Levine’s performance, then took home the award for favorite pop/rock male beating out past crowd favorites Justin Bieber and Pitbull.

"I just want to share this award with Justin Bieber and Pitbull,” said the “Grenade” star humbly. “This is all our work."

Taylor Swift won artist of the year for the second time (she won back in 2009.) She also was awarded AMA’s for favorite “Country Star” and favorite “Country Album” and thanked Selena Gomez for it.

“I love my fans and family and Selena Gomez the little sister I never had," said an emotional Swift. “This is so crazy!”

“I ended up writing the record by myself, so the fact that you would honor it this way, you have no idea what this means to me."

After singing “On the Floor” with the curvaceous Jennifer Lopez, Pitbull stood by her ex-husband Marc Anthony singing their latest single “Rain Over Me,” while rapper Lil Jon DJ-ed the song.

Enrique Iglesias and Ludacris got the crown dancing to “Tonight (I’m Lovin’ You) with a choir in the background. Iglesias graciously kissed and huged JLO as she dethroned him , winning the AMA for favorite “Latin Artist” of  the year.
